Overview

An API client for SQS. To construct a client, you need to configure a :region and :credentials.

client = Aws::SQS::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials used for authentication. This can be any class that includes and implements Aws::CredentialProvider, or instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::SharedCredentials - Used for loading static credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

    • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

    • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

    • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]

    • The :access_key_id, :secret_access_key, :session_token, and :account_id options.

    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'], ENV['AWS_SESSION_TOKEN'], and ENV['AWS_ACCOUNT_ID'].

    • ~/.aws/credentials

    • ~/.aws/config

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive.

Instance Method Details

#add_permission(params = {}) ⇒ Struct

Adds a permission to a queue for a specific principal. This allows sharing access to the queue.

When you create a queue, you have full control access rights for the queue. Only you, the owner of the queue, can grant or deny permissions to the queue. For more information about these permissions, see Allow Developers to Write Messages to a Shared Queue in the Amazon SQS Developer Guide.

* AddPermission generates a policy for you. You can use SetQueueAttributes to upload your policy. For more information, see Using Custom Policies with the Amazon SQS Access Policy Language in the Amazon SQS Developer Guide.

  • An Amazon SQS policy can have a maximum of seven actions per statement.

  • To remove the ability to change queue permissions, you must deny permission to the AddPermission, RemovePermission, and SetQueueAttributes actions in your IAM policy.

  • Amazon SQS AddPermission does not support adding a non-account principal.

Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide.

Examples:

Request syntax with placeholder values


resp = client.add_permission({
  queue_url: "String", # required
  label: "String", # required
  aws_account_ids: ["String"], # required
  actions: ["String"], # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue to which permissions are added.

    Queue URLs and names are case-sensitive.

  • :label (required, String) —

    The unique identification of the permission you're setting (for example, AliceSendMessage). Maximum 80 characters. Allowed characters include alphanumeric characters, hyphens (-), and underscores (_).

  • :aws_account_ids (required, Array<String>) —

    The Amazon Web Services account numbers of the principals who are to receive permission. For information about locating the Amazon Web Services account identification, see Your Amazon Web Services Identifiers in the Amazon SQS Developer Guide.

  • :actions (required, Array<String>) —

    The action the client wants to allow for the specified principal. Valid values: the name of any action or *.

    For more information about these actions, see Overview of Managing Access Permissions to Your Amazon Simple Queue Service Resource in the Amazon SQS Developer Guide.

    Specifying SendMessage, DeleteMessage, or ChangeMessageVisibility for ActionName.n also grants permissions for the corresponding batch versions of those actions: SendMessageBatch, DeleteMessageBatch, and ChangeMessageVisibilityBatch.

Returns:

  • (Struct) —

    Returns an empty response.

#cancel_message_move_task(params = {}) ⇒ Types::CancelMessageMoveTaskResult

Cancels a specified message movement task. A message movement can only be cancelled when the current status is RUNNING. Cancelling a message movement task does not revert the messages that have already been moved. It can only stop the messages that have not been moved yet.

* This action is currently limited to supporting message redrive from dead-letter queues (DLQs) only. In this context, the source queue is the dead-letter queue (DLQ), while the destination queue can be the original source queue (from which the messages were driven to the dead-letter-queue), or a custom destination queue.

  • Only one active message movement task is supported per queue at any given time.

Examples:

Request syntax with placeholder values


resp = client.cancel_message_move_task({
  task_handle: "String", # required
})

Response structure


resp.approximate_number_of_messages_moved #=> Integer

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :task_handle (required, String) —

    An identifier associated with a message movement task.

Returns:

#change_message_visibility(params = {}) ⇒ Struct

Changes the visibility timeout of a specified message in a queue to a new value. The default visibility timeout for a message is 30 seconds. The minimum is 0 seconds. The maximum is 12 hours. For more information, see Visibility Timeout in the Amazon SQS Developer Guide.

For example, if the default timeout for a queue is 60 seconds, 15 seconds have elapsed since you received the message, and you send a ChangeMessageVisibility call with VisibilityTimeout set to 10 seconds, the 10 seconds begin to count from the time that you make the ChangeMessageVisibility call. Thus, any attempt to change the visibility timeout or to delete that message 10 seconds after you initially change the visibility timeout (a total of 25 seconds) might result in an error.

An Amazon SQS message has three basic states:

  1. Sent to a queue by a producer.

  2. Received from the queue by a consumer.

  3. Deleted from the queue.

A message is considered to be stored after it is sent to a queue by a producer, but not yet received from the queue by a consumer (that is, between states 1 and 2). There is no limit to the number of stored messages. A message is considered to be in flight after it is received from a queue by a consumer, but not yet deleted from the queue (that is, between states 2 and 3). There is a limit to the number of in flight messages.

Limits that apply to in flight messages are unrelated to the unlimited number of stored messages.

For most standard queues (depending on queue traffic and message backlog), there can be a maximum of approximately 120,000 in flight messages (received from a queue by a consumer, but not yet deleted from the queue). If you reach this limit, Amazon SQS returns the OverLimit error message. To avoid reaching the limit, you should delete messages from the queue after they're processed. You can also increase the number of queues you use to process your messages. To request a limit increase, file a support request.

For FIFO queues, there can be a maximum of 120,000 in flight messages (received from a queue by a consumer, but not yet deleted from the queue). If you reach this limit, Amazon SQS returns no error messages.

If you attempt to set the VisibilityTimeout to a value greater than the maximum time left, Amazon SQS returns an error. Amazon SQS doesn't automatically recalculate and increase the timeout to the maximum remaining time.

Unlike with a queue, when you change the visibility timeout for a specific message the timeout value is applied immediately but isn't saved in memory for that message. If you don't delete a message after it is received, the visibility timeout for the message reverts to the original timeout value (not to the value you set using the ChangeMessageVisibility action) the next time the message is received.

Examples:

Request syntax with placeholder values


resp = client.change_message_visibility({
  queue_url: "String", # required
  receipt_handle: "String", # required
  visibility_timeout: 1, # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue whose message's visibility is changed.

    Queue URLs and names are case-sensitive.

  • :receipt_handle (required, String) —

    The receipt handle associated with the message, whose visibility timeout is changed. This parameter is returned by the ReceiveMessage action.

  • :visibility_timeout (required, Integer) —

    The new value for the message's visibility timeout (in seconds). Values range: 0 to 43200. Maximum: 12 hours.

Returns:

  • (Struct) —

    Returns an empty response.

def change_message_visibility: (

#change_message_visibility_batch(params = {}) ⇒ Types::ChangeMessageVisibilityBatchResult

Changes the visibility timeout of multiple messages. This is a batch version of ChangeMessageVisibility. The result of the action on each message is reported individually in the response. You can send up to 10 ChangeMessageVisibility requests with each ChangeMessageVisibilityBatch action.

Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of 200.

Examples:

Request syntax with placeholder values


resp = client.change_message_visibility_batch({
  queue_url: "String", # required
  entries: [ # required
    {
      id: "String", # required
      receipt_handle: "String", # required
      visibility_timeout: 1,
    },
  ],
})

resp.failed #=> Array
resp.failed[0].id #=> String
resp.failed[0].sender_fault #=> Boolean
resp.failed[0].code #=> String
resp.failed[0].message #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue whose messages' visibility is changed.

    Queue URLs and names are case-sensitive.

  • :entries (required, Array<Types::ChangeMessageVisibilityBatchRequestEntry>) —

    Lists the receipt handles of the messages for which the visibility timeout must be changed.

#create_queue(params = {}) ⇒ Types::CreateQueueResult

Creates a new standard or FIFO queue. You can pass one or more attributes in the request. Keep the following in mind:

  • If you don't specify the FifoQueue attribute, Amazon SQS creates a standard queue.

    You can't change the queue type after you create it and you can't convert an existing standard queue into a FIFO queue. You must either create a new FIFO queue for your application or delete your existing standard queue and recreate it as a FIFO queue. For more information, see Moving From a standard queue to a FIFO queue in the Amazon SQS Developer Guide.

  • If you don't provide a value for an attribute, the queue is created with the default value for the attribute.

  • If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.

To successfully create a new queue, you must provide a queue name that adheres to the limits related to queues and is unique within the scope of your queues.

After you create a queue, you must wait at least one second after the queue is created to be able to use the queue.

To retrieve the URL of a queue, use the GetQueueUrl action. This action only requires the QueueName parameter.

When creating queues, keep the following points in mind:

  • If you specify the name of an existing queue and provide the exact same names and values for all its attributes, the CreateQueue action will return the URL of the existing queue instead of creating a new one.

  • If you attempt to create a queue with a name that already exists but with different attribute names or values, the CreateQueue action will return an error. This ensures that existing queues are not inadvertently altered.

Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide.

Examples:

Request syntax with placeholder values


resp = client.create_queue({
  queue_name: "String", # required
  attributes: {
    "All" => "String",
  },
  tags: {
    "TagKey" => "TagValue",
  },
})

Response structure


resp.queue_url #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_name (required, String) —

    The name of the new queue. The following limits apply to this name:

    • A queue name can have up to 80 characters.

    • Valid values: alphanumeric characters, hyphens (-), and underscores (_).

    • A FIFO queue name must end with the .fifo suffix.

    Queue URLs and names are case-sensitive.

  • :attributes (Hash<String,String>) —

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the CreateQueue action uses:

    • DelaySeconds – The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 seconds (15 minutes). Default: 0.

    • MaximumMessageSize – The limit of how many bytes a message can contain before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes (1 KiB) to 1,048,576 bytes (1 MiB). Default: 1,048,576 bytes (1 MiB).

    • MessageRetentionPeriod – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer from 60 seconds (1 minute) to 1,209,600 seconds (14 days). Default: 345,600 (4 days). When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the MessageRetentionPeriod attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the MessageRetentionPeriod is reduced below the age of existing messages.

    • Policy – The queue's policy. A valid Amazon Web Services policy. For more information about policy structure, see Overview of Amazon Web Services IAM Policies in the IAM User Guide.

    • ReceiveMessageWaitTimeSeconds – The length of time, in seconds, for which a ReceiveMessage action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.

    • VisibilityTimeout – The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide.

    The following attributes apply only to dead-letter queues:

    • RedrivePolicy – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. The parameters are as follows:

    • deadLetterTargetArn – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of maxReceiveCount is exceeded.

    • maxReceiveCount – The number of times a message is delivered to the source queue before being moved to the dead-letter queue. Default: 10. When the ReceiveCount for a message exceeds the maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.

    • RedriveAllowPolicy – The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:

    • redrivePermission – The permission type that defines which source queues can specify the current queue as the dead-letter queue. Valid values are:

      • allowAll – (Default) Any source queues in this Amazon Web Services account in the same Region can specify this queue as the dead-letter queue.

      • denyAll – No source queues can specify this queue as the dead-letter queue.

      • byQueue – Only queues specified by the sourceQueueArns parameter can specify this queue as the dead-letter queue.

    • sourceQueueArns – The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when the redrivePermission parameter is set to byQueue. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set the redrivePermission parameter to allowAll.

    The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.

    The following attributes apply only to server-side-encryption:

    • KmsMasterKeyId – The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms. While the alias of the Amazon Web Services managed CMK for Amazon SQS is always alias/aws/sqs, the alias of a custom CMK can, for example, be alias/MyAlias . For more examples, see KeyId in the Key Management Service API Reference.

    • KmsDataKeyReusePeriodSeconds – The length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt messages before calling KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier. For more information, see How Does the Data Key Reuse Period Work?

    • SqsManagedSseEnabled – Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS).

    The following attributes apply only to FIFO (first-in-first-out) queues:

    • FifoQueue – Designates a queue as FIFO. Valid values are true and false. If you don't specify the FifoQueue attribute, Amazon SQS creates a standard queue. You can provide this attribute only during queue creation. You can't change it for an existing queue. When you set this attribute, you must also provide the MessageGroupId for your messages explicitly.

      For more information, see FIFO queue logic in the Amazon SQS Developer Guide.

    • ContentBasedDeduplication – Enables content-based deduplication. Valid values are true and false. For more information, see Exactly-once processing in the Amazon SQS Developer Guide. Note the following:

    • Every message must have a unique MessageDeduplicationId.

      • You may provide a MessageDeduplicationId explicitly.

      • If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).

      • If you don't provide a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error.

      • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.

    • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.

    • If you send one message with ContentBasedDeduplication enabled and then another message with a MessageDeduplicationId that is the same as the one generated for the first MessageDeduplicationId, the two messages are treated as duplicates and only one copy of the message is delivered.

    The following attributes apply only to high throughput for FIFO queues:

    • DeduplicationScope – Specifies whether message deduplication occurs at the message group or queue level. Valid values are messageGroup and queue.

    • FifoThroughputLimit – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are perQueue and perMessageGroupId. The perMessageGroupId value is allowed only when the value for DeduplicationScope is messageGroup.

    To enable high throughput for FIFO queues, do the following:

    • Set DeduplicationScope to messageGroup.

    • Set FifoThroughputLimit to perMessageGroupId.

    If you set these attributes to anything other than the values shown for enabling high throughput, normal throughput is in effect and deduplication occurs as specified.

    For information on throughput quotas, see Quotas related to messages in the Amazon SQS Developer Guide.

  • :tags (Hash<String,String>) —

    Add cost allocation tags to the specified Amazon SQS queue. For an overview, see Tagging Your Amazon SQS Queues in the Amazon SQS Developer Guide.

    When you use queue tags, keep the following guidelines in mind:

    • Adding more than 50 tags to a queue isn't recommended.

    • Tags don't have any semantic meaning. Amazon SQS interprets tags as character strings.

    • Tags are case-sensitive.

    • A new tag with a key identical to that of an existing tag overwrites the existing tag.

    For a full list of tag restrictions, see Quotas related to queues in the Amazon SQS Developer Guide.

    To be able to tag a queue on creation, you must have the sqs:CreateQueue and sqs:TagQueue permissions.

    Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide.

def create_queue: (

#delete_message(params = {}) ⇒ Struct

Deletes the specified message from the specified queue. To select the message to delete, use the ReceiptHandle of the message (not the MessageId which you receive when you send the message). Amazon SQS can delete a message from a queue even if a visibility timeout setting causes the message to be locked by another consumer. Amazon SQS automatically deletes messages left in a queue longer than the retention period configured for the queue.

Each time you receive a message, meaning when a consumer retrieves a message from the queue, it comes with a unique ReceiptHandle. If you receive the same message more than once, you will get a different ReceiptHandle each time. When you want to delete a message using the DeleteMessage action, you must use the ReceiptHandle from the most recent time you received the message. If you use an old ReceiptHandle, the request will succeed, but the message might not be deleted.

For standard queues, it is possible to receive a message even after you delete it. This might happen on rare occasions if one of the servers which stores a copy of the message is unavailable when you send the request to delete the message. The copy remains on the server and might be returned to you during a subsequent receive request. You should ensure that your application is idempotent, so that receiving a message more than once does not cause issues.

Examples:

Request syntax with placeholder values


resp = client.delete_message({
  queue_url: "String", # required
  receipt_handle: "String", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue from which messages are deleted.

    Queue URLs and names are case-sensitive.

  • :receipt_handle (required, String) —

    The receipt handle associated with the message to delete.

Returns:

  • (Struct) —

    Returns an empty response.

# File 'sig/client.rbs', line 142

def delete_message: (

#delete_message_batch(params = {}) ⇒ Types::DeleteMessageBatchResult

Deletes up to ten messages from the specified queue. This is a batch version of DeleteMessage. The result of the action on each message is reported individually in the response.

Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of 200.

Examples:

Request syntax with placeholder values


resp = client.delete_message_batch({
  queue_url: "String", # required
  entries: [ # required
    {
      id: "String", # required
      receipt_handle: "String", # required
    },
  ],
})

Response structure


resp.successful #=> Array
resp.successful[0].id #=> String
resp.failed #=> Array
resp.failed[0].id #=> String
resp.failed[0].sender_fault #=> Boolean
resp.failed[0].code #=> String
resp.failed[0].message #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue from which messages are deleted.

    Queue URLs and names are case-sensitive.

  • :entries (required, Array<Types::DeleteMessageBatchRequestEntry>) —

    Lists the receipt handles for the messages to be deleted.

Returns:

# File 'sig/client.rbs', line 154

def delete_message_batch: (

#delete_queue(params = {}) ⇒ Struct

Deletes the queue specified by the QueueUrl, regardless of the queue's contents.

Be careful with the DeleteQueue action: When you delete a queue, any messages in the queue are no longer available.

When you delete a queue, the deletion process takes up to 60 seconds. Requests you send involving that queue during the 60 seconds might succeed. For example, a SendMessage request might succeed, but after 60 seconds the queue and the message you sent no longer exist.

When you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.

Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide.

The delete operation uses the HTTP GET verb.

Examples:

Request syntax with placeholder values


resp = client.delete_queue({
  queue_url: "String", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue to delete.

    Queue URLs and names are case-sensitive.

Returns:

  • (Struct) —

    Returns an empty response.

# File 'sig/client.rbs', line 166

def delete_queue: (

#get_queue_attributes(params = {}) ⇒ Types::GetQueueAttributesResult

Gets attributes for the specified queue.

To determine whether a queue is FIFO, you can check whether QueueName ends with the .fifo suffix.

Examples:

Request syntax with placeholder values


resp = client.get_queue_attributes({
  queue_url: "String", # required
  attribute_names: ["All"], # accepts All, Policy, VisibilityTimeout, MaximumMessageSize, MessageRetentionPeriod, ApproximateNumberOfMessages, ApproximateNumberOfMessagesNotVisible, CreatedTimestamp, LastModifiedTimestamp, QueueArn, ApproximateNumberOfMessagesDelayed, DelaySeconds, ReceiveMessageWaitTimeSeconds, RedrivePolicy, FifoQueue, ContentBasedDeduplication, KmsMasterKeyId, KmsDataKeyReusePeriodSeconds, DeduplicationScope, FifoThroughputLimit, RedriveAllowPolicy, SqsManagedSseEnabled
})

Response structure


resp.attributes #=> Hash
resp.attributes["QueueAttributeName"] #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue whose attribute information is retrieved.

    Queue URLs and names are case-sensitive.

  • :attribute_names (Array<String>) —

    A list of attributes for which to retrieve information.

    The AttributeNames parameter is optional, but if you don't specify values for this parameter, the request returns empty results.

    In the future, new attributes might be added. If you write code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

    The following attributes are supported:

    The ApproximateNumberOfMessagesDelayed, ApproximateNumberOfMessagesNotVisible, and ApproximateNumberOfMessages metrics may not achieve consistency until at least 1 minute after the producers stop sending messages. This period is required for the queue metadata to reach eventual consistency.

    • All – Returns all values.

    • ApproximateNumberOfMessages – Returns the approximate number of messages available for retrieval from the queue.

    • ApproximateNumberOfMessagesDelayed – Returns the approximate number of messages in the queue that are delayed and not available for reading immediately. This can happen when the queue is configured as a delay queue or when a message has been sent with a delay parameter.

    • ApproximateNumberOfMessagesNotVisible – Returns the approximate number of messages that are in flight. Messages are considered to be in flight if they have been sent to a client but have not yet been deleted or have not yet reached the end of their visibility window.

    • CreatedTimestamp – Returns the time when the queue was created in seconds (epoch time).

    • DelaySeconds – Returns the default delay on the queue in seconds.

    • LastModifiedTimestamp – Returns the time when the queue was last changed in seconds (epoch time).

    • MaximumMessageSize – Returns the limit of how many bytes a message can contain before Amazon SQS rejects it.

    • MessageRetentionPeriod – Returns the length of time, in seconds, for which Amazon SQS retains a message. When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the MessageRetentionPeriod attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the MessageRetentionPeriod is reduced below the age of existing messages.

    • Policy – Returns the policy of the queue.

    • QueueArn – Returns the Amazon resource name (ARN) of the queue.

    • ReceiveMessageWaitTimeSeconds – Returns the length of time, in seconds, for which the ReceiveMessage action waits for a message to arrive.

    • VisibilityTimeout – Returns the visibility timeout for the queue. For more information about the visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide.

    The following attributes apply only to dead-letter queues:

    • RedrivePolicy – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. The parameters are as follows:

    • deadLetterTargetArn – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of maxReceiveCount is exceeded.

    • maxReceiveCount – The number of times a message is delivered to the source queue before being moved to the dead-letter queue. Default: 10. When the ReceiveCount for a message exceeds the maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.

    • RedriveAllowPolicy – The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:

    • redrivePermission – The permission type that defines which source queues can specify the current queue as the dead-letter queue. Valid values are:

      • allowAll – (Default) Any source queues in this Amazon Web Services account in the same Region can specify this queue as the dead-letter queue.

      • denyAll – No source queues can specify this queue as the dead-letter queue.

      • byQueue – Only queues specified by the sourceQueueArns parameter can specify this queue as the dead-letter queue.

    • sourceQueueArns – The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when the redrivePermission parameter is set to byQueue. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set the redrivePermission parameter to allowAll.

    The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.

    The following attributes apply only to server-side-encryption:

    • KmsMasterKeyId – Returns the ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms.

    • KmsDataKeyReusePeriodSeconds – Returns the length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt messages before calling KMS again. For more information, see How Does the Data Key Reuse Period Work?.

    • SqsManagedSseEnabled – Returns information about whether the queue is using SSE-SQS encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS).

    The following attributes apply only to FIFO (first-in-first-out) queues:

    • FifoQueue – Returns information about whether the queue is FIFO. For more information, see FIFO queue logic in the Amazon SQS Developer Guide.

      To determine whether a queue is FIFO, you can check whether QueueName ends with the .fifo suffix.

    • ContentBasedDeduplication – Returns whether content-based deduplication is enabled for the queue. For more information, see Exactly-once processing in the Amazon SQS Developer Guide.

    The following attributes apply only to high throughput for FIFO queues:

    • DeduplicationScope – Specifies whether message deduplication occurs at the message group or queue level. Valid values are messageGroup and queue.

    • FifoThroughputLimit – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are perQueue and perMessageGroupId. The perMessageGroupId value is allowed only when the value for DeduplicationScope is messageGroup.

    To enable high throughput for FIFO queues, do the following:

    • Set DeduplicationScope to messageGroup.

    • Set FifoThroughputLimit to perMessageGroupId.

    If you set these attributes to anything other than the values shown for enabling high throughput, normal throughput is in effect and deduplication occurs as specified.

    For information on throughput quotas, see Quotas related to messages in the Amazon SQS Developer Guide.

def list_queues: (

#purge_queue(params = {}) ⇒ Struct

Deletes available messages in a queue (including in-flight messages) specified by the QueueURL parameter.

When you use the PurgeQueue action, you can't retrieve any messages deleted from a queue.

The message deletion process takes up to 60 seconds. We recommend waiting for 60 seconds regardless of your queue's size.

Messages sent to the queue before you call PurgeQueue might be received but are deleted within the next minute.

Messages sent to the queue after you call PurgeQueue might be deleted while the queue is being purged.

Examples:

resp = client.purge_queue({
  queue_url: "String", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the queue from which the PurgeQueue action deletes messages.

    Queue URLs and names are case-sensitive.

Returns:

  • (Struct) —

    Returns an empty response.

def purge_queue: (

#receive_message(params = {}) ⇒ Types::ReceiveMessageResult

Retrieves one or more messages (up to 10), from the specified queue. Using the WaitTimeSeconds parameter enables long-poll support. For more information, see Amazon SQS Long Polling in the Amazon SQS Developer Guide.

Short poll is the default behavior where a weighted random set of machines is sampled on a ReceiveMessage call. Therefore, only the messages on the sampled machines are returned. If the number of messages in the queue is small (fewer than 1,000), you most likely get fewer messages than you requested per ReceiveMessage call. If the number of messages in the queue is extremely small, you might not receive any messages in a particular ReceiveMessage response. If this happens, repeat the request.

For each message returned, the response includes the following:

  • The message body.

  • An MD5 digest of the message body. For information about MD5, see RFC1321.

  • The MessageId you received when you sent the message to the queue.

  • The receipt handle.

  • The message attributes.

  • An MD5 digest of the message attributes.

The receipt handle is the identifier you must provide when deleting the message. For more information, see Queue and Message Identifiers in the Amazon SQS Developer Guide.

You can provide the VisibilityTimeout parameter in your request. The parameter is applied to the messages that Amazon SQS returns in the response. If you don't include the parameter, the overall visibility timeout for the queue is used for the returned messages. The default visibility timeout for a queue is 30 seconds.

In the future, new attributes might be added. If you write code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

Examples:

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue from which messages are received.

    Queue URLs and names are case-sensitive.

  • :attribute_names (Array<String>) —

    This parameter has been discontinued but will be supported for backward compatibility. To provide attribute names, you are encouraged to use MessageSystemAttributeNames.

    A list of attributes that need to be returned along with each message. These attributes include:

    • All – Returns all values.

    • ApproximateFirstReceiveTimestamp – Returns the time the message was first received from the queue (epoch time in milliseconds).

    • ApproximateReceiveCount – Returns the number of times a message has been received across all queues but not deleted.

    • AWSTraceHeader – Returns the X-Ray trace header string.

    • SenderId

    • For a user, returns the user ID, for example ABCDEFGHI1JKLMNOPQ23R.

    • For an IAM role, returns the IAM role ID, for example ABCDE1F2GH3I4JK5LMNOP:i-a123b456.

    • SentTimestamp – Returns the time the message was sent to the queue (epoch time in milliseconds).

    • SqsManagedSseEnabled – Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS).

    • MessageDeduplicationId – Returns the value provided by the producer that calls the SendMessage action.

    • MessageGroupId – Returns the value provided by the producer that calls the SendMessage action.

    • SequenceNumber – Returns the value provided by Amazon SQS.

  • :message_system_attribute_names (Array<String>) —

    A list of attributes that need to be returned along with each message. These attributes include:

    • All – Returns all values.

    • ApproximateFirstReceiveTimestamp – Returns the time the message was first received from the queue (epoch time in milliseconds).

    • ApproximateReceiveCount – Returns the number of times a message has been received across all queues but not deleted.

    • AWSTraceHeader – Returns the X-Ray trace header string.

    • SenderId

    • For a user, returns the user ID, for example ABCDEFGHI1JKLMNOPQ23R.

    • For an IAM role, returns the IAM role ID, for example ABCDE1F2GH3I4JK5LMNOP:i-a123b456.

    • SentTimestamp – Returns the time the message was sent to the queue (epoch time in milliseconds).

    • SqsManagedSseEnabled – Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS).

    • MessageDeduplicationId – Returns the value provided by the producer that calls the SendMessage action.

    • MessageGroupId – Returns the value provided by the producer that calls the SendMessage action.

    • SequenceNumber – Returns the value provided by Amazon SQS.

  • :message_attribute_names (Array<String>) —

    The name of the message attribute, where N is the index.

    • The name can contain alphanumeric characters and the underscore (_), hyphen (-), and period (.).

    • The name is case-sensitive and must be unique among all attribute names for the message.

    • The name must not start with AWS-reserved prefixes such as AWS. or Amazon. (or any casing variants).

    • The name must not start or end with a period (.), and it should not have periods in succession (..).

    • The name can be up to 256 characters long.

    When using ReceiveMessage, you can send a list of attribute names to receive, or you can return all of the attributes by specifying All or .* in your request. You can also use all message attributes starting with a prefix, for example bar.*.

  • :max_number_of_messages (Integer) —

    The maximum number of messages to return. Amazon SQS never returns more messages than this value (however, fewer messages might be returned). Valid values: 1 to 10. Default: 1.

  • :visibility_timeout (Integer) —

    The duration (in seconds) that the received messages are hidden from subsequent retrieve requests after being retrieved by a ReceiveMessage request. If not specified, the default visibility timeout for the queue is used, which is 30 seconds.

    Understanding VisibilityTimeout:

    • When a message is received from a queue, it becomes temporarily invisible to other consumers for the duration of the visibility timeout. This prevents multiple consumers from processing the same message simultaneously. If the message is not deleted or its visibility timeout is not extended before the timeout expires, it becomes visible again and can be retrieved by other consumers.

    • Setting an appropriate visibility timeout is crucial. If it's too short, the message might become visible again before processing is complete, leading to duplicate processing. If it's too long, it delays the reprocessing of messages if the initial processing fails.

    • You can adjust the visibility timeout using the --visibility-timeout parameter in the receive-message command to match the processing time required by your application.

    • A message that isn't deleted or a message whose visibility isn't extended before the visibility timeout expires counts as a failed receive. Depending on the configuration of the queue, the message might be sent to the dead-letter queue.

    For more information, see Visibility Timeout in the Amazon SQS Developer Guide.

  • :wait_time_seconds (Integer) —

    The duration (in seconds) for which the call waits for a message to arrive in the queue before returning. If a message is available, the call returns sooner than WaitTimeSeconds. If no messages are available and the wait time expires, the call does not return a message list. If you are using the Java SDK, it returns a ReceiveMessageResponse object, which has a empty list instead of a Null object.

    To avoid HTTP errors, ensure that the HTTP response timeout for ReceiveMessage requests is longer than the WaitTimeSeconds parameter. For example, with the Java SDK, you can set HTTP transport settings using the NettyNioAsyncHttpClient for asynchronous clients, or the ApacheHttpClient for synchronous clients.

  • :receive_request_attempt_id (String) —

    This parameter applies only to FIFO (first-in-first-out) queues.

    The token used for deduplication of ReceiveMessage calls. If a networking issue occurs after a ReceiveMessage action, and instead of a response you receive a generic error, it is possible to retry the same action with an identical ReceiveRequestAttemptId to retrieve the same set of messages, even if their visibility timeout has not yet expired.

    • You can use ReceiveRequestAttemptId only for 5 minutes after a ReceiveMessage action.

    • When you set FifoQueue, a caller of the ReceiveMessage action can provide a ReceiveRequestAttemptId explicitly.

    • It is possible to retry the ReceiveMessage action with the same ReceiveRequestAttemptId if none of the messages have been modified (deleted or had their visibility changes).

    • During a visibility timeout, subsequent calls with the same ReceiveRequestAttemptId return the same messages and receipt handles. If a retry occurs within the deduplication interval, it resets the visibility timeout. For more information, see Visibility Timeout in the Amazon SQS Developer Guide.

      If a caller of the ReceiveMessage action still processes messages when the visibility timeout expires and messages become visible, another worker consuming from the same queue can receive the same messages and therefore process duplicates. Also, if a consumer whose message processing time is longer than the visibility timeout tries to delete the processed messages, the action fails with an error.

      To mitigate this effect, ensure that your application observes a safe threshold before the visibility timeout expires and extend the visibility timeout as necessary.

    • While messages with a particular MessageGroupId are invisible, no more messages belonging to the same MessageGroupId are returned until the visibility timeout expires. You can still receive messages with another MessageGroupId from your FIFO queue as long as they are visible.

    • If a caller of ReceiveMessage can't track the ReceiveRequestAttemptId, no retries work until the original visibility timeout expires. As a result, delays might occur but the messages in the queue remain in a strict order.

    The maximum length of ReceiveRequestAttemptId is 128 characters. ReceiveRequestAttemptId can contain alphanumeric characters (a-z, A-Z, 0-9) and punctuation (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~).

    For best practices of using ReceiveRequestAttemptId, see Using the ReceiveRequestAttemptId Request Parameter in the Amazon SQS Developer Guide.

#remove_permission(params = {}) ⇒ Struct

Revokes any permissions in the queue policy that matches the specified Label parameter.

* Only the owner of a queue can remove permissions from it.

  • Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide.

  • To remove the ability to change queue permissions, you must deny permission to the AddPermission, RemovePermission, and SetQueueAttributes actions in your IAM policy.

Examples:

Request syntax with placeholder values


resp = client.remove_permission({
  queue_url: "String", # required
  label: "String", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue from which permissions are removed.

    Queue URLs and names are case-sensitive.

  • :label (required, String) —

    The identification of the permission to remove. This is the label added using the AddPermission action.

Returns:

#send_message(params = {}) ⇒ Types::SendMessageResult

Delivers a message to the specified queue.

A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed. For more information, see the W3C specification for characters.

#x9 | #xA | #xD | #x20 to #xD7FF | #xE000 to #xFFFD | #x10000 to #x10FFFF

If a message contains characters outside the allowed set, Amazon SQS rejects the message and returns an InvalidMessageContents error. Ensure that your message body includes only valid characters to avoid this exception.

Examples:

Request syntax with placeholder values


resp = client.send_message({
  queue_url: "String", # required
  message_body: "String", # required
  delay_seconds: 1,
  message_attributes: {

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue to which a message is sent.

    Queue URLs and names are case-sensitive.

  • :message_body (required, String) —

    The message to send. The minimum size is one character. The maximum size is 1 MiB or 1,048,576 bytes

    A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed. For more information, see the W3C specification for characters.

    #x9 | #xA | #xD | #x20 to #xD7FF | #xE000 to #xFFFD | #x10000 to #x10FFFF

    If a message contains characters outside the allowed set, Amazon SQS rejects the message and returns an InvalidMessageContents error. Ensure that your message body includes only valid characters to avoid this exception.

  • :delay_seconds (Integer) —

    The length of time, in seconds, for which to delay a specific message. Valid values: 0 to 900. Maximum: 15 minutes. Messages with a positive DelaySeconds value become available for processing after the delay period is finished. If you don't specify a value, the default value for the queue applies.

    When you set FifoQueue, you can't set DelaySeconds per message. You can set this parameter only on a queue level.

  • :message_attributes (Hash<String,Types::MessageAttributeValue>) —

    Each message attribute consists of a Name, Type, and Value. For more information, see Amazon SQS message attributes in the Amazon SQS Developer Guide.

  • :message_system_attributes (Hash<String,Types::MessageSystemAttributeValue>) —

    The message system attribute to send. Each message system attribute consists of a Name, Type, and Value.

    • Currently, the only supported message system attribute is AWSTraceHeader. Its type must be String and its value must be a correctly formatted X-Ray trace header string.

    • The size of a message system attribute doesn't count towards the total size of a message.

  • :message_deduplication_id (String) —

    This parameter applies only to FIFO (first-in-first-out) queues.

    The token used for deduplication of sent messages. If a message with a particular MessageDeduplicationId is sent successfully, any messages sent with the same MessageDeduplicationId are accepted successfully but aren't delivered during the 5-minute deduplication interval. For more information, see Exactly-once processing in the Amazon SQS Developer Guide.

    • Every message must have a unique MessageDeduplicationId,

    • You may provide a MessageDeduplicationId explicitly.

    • If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).

    • If you don't provide a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error.

    • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.

    • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.

    • If you send one message with ContentBasedDeduplication enabled and then another message with a MessageDeduplicationId that is the same as the one generated for the first MessageDeduplicationId, the two messages are treated as duplicates and only one copy of the message is delivered.

    The MessageDeduplicationId is available to the consumer of the message (this can be useful for troubleshooting delivery issues).

    If a message is sent successfully but the acknowledgement is lost and the message is resent with the same MessageDeduplicationId after the deduplication interval, Amazon SQS can't detect duplicate messages.

    Amazon SQS continues to keep track of the message deduplication ID even after the message is received and deleted.

    The maximum length of MessageDeduplicationId is 128 characters. MessageDeduplicationId can contain alphanumeric characters (a-z, A-Z, 0-9) and punctuation (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~).

    For best practices of using MessageDeduplicationId, see Using the MessageDeduplicationId Property in the Amazon SQS Developer Guide.

  • :message_group_id (String) —

    MessageGroupId is an attribute used in Amazon SQS FIFO (First-In-First-Out) and standard queues. In FIFO queues, MessageGroupId organizes messages into distinct groups. Messages within the same message group are always processed one at a time, in strict order, ensuring that no two messages from the same group are processed simultaneously. In standard queues, using MessageGroupId enables fair queues. It is used to identify the tenant a message belongs to, helping maintain consistent message dwell time across all tenants during noisy neighbor events. Unlike FIFO queues, messages with the same MessageGroupId can be processed in parallel, maintaining the high throughput of standard queues.

    • FIFO queues: MessageGroupId acts as the tag that specifies that a message belongs to a specific message group. Messages that belong to the same message group are processed in a FIFO manner (however, messages in different message groups might be processed out of order). To interleave multiple ordered streams within a single queue, use MessageGroupId values (for example, session data for multiple users). In this scenario, multiple consumers can process the queue, but the session data of each user is processed in a FIFO fashion.

      If you do not provide a MessageGroupId when sending a message to a FIFO queue, the action fails.

      ReceiveMessage might return messages with multiple MessageGroupId values. For each MessageGroupId, the messages are sorted by time sent.

    • **Standard queues:**Use MessageGroupId in standard queues to enable fair queues. The MessageGroupId identifies the tenant a message belongs to. A tenant can be any entity that shares a queue with others, such as your customer, a client application, or a request type. When one tenant sends a disproportionately large volume of messages or has messages that require longer processing time, fair queues ensure other tenants' messages maintain low dwell time. This preserves quality of service for all tenants while maintaining the scalability and throughput of standard queues. We recommend that you include a MessageGroupId in all messages when using fair queues.

    The length of MessageGroupId is 128 characters. Valid values: alphanumeric characters and punctuation (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~).

    For best practices of using MessageGroupId, see Using the MessageGroupId Property in the Amazon SQS Developer Guide.

def send_message: (

#send_message_batch(params = {}) ⇒ Types::SendMessageBatchResult

You can use SendMessageBatch to send up to 10 messages to the specified queue by assigning either identical or different values to each message (or by not assigning values at all). This is a batch version of SendMessage. For a FIFO queue, multiple messages within a single batch are enqueued in the order they are sent.

The result of sending each message is reported individually in the response. Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of 200.

The maximum allowed individual message size and the maximum total payload size (the sum of the individual lengths of all of the batched messages) are both 1 MiB 1,048,576 bytes.

A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed. For more information, see the W3C specification for characters.

#x9 | #xA | #xD | #x20 to #xD7FF | #xE000 to #xFFFD | #x10000 to #x10FFFF

If a message contains characters outside the allowed set, Amazon SQS rejects the message and returns an InvalidMessageContents error. Ensure that your message body includes only valid characters to avoid this exception.

If you don't specify the DelaySeconds parameter for an entry, Amazon SQS uses the default value for the queue.

Examples:

Request syntax with placeholder values


resp = client.send_message_batch({

#set_queue_attributes(params = {}) ⇒ Struct

Sets the value of one or more queue attributes, like a policy. When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the MessageRetentionPeriod attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the MessageRetentionPeriod is reduced below the age of existing messages.

* In the future, new attributes might be added. If you write code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

  • Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide.

  • To remove the ability to change queue permissions, you must deny permission to the AddPermission, RemovePermission, and SetQueueAttributes actions in your IAM policy.

Examples:

Request syntax with placeholder values


resp = client.set_queue_attributes({
  queue_url: "String", # required
  attributes: { # required
    "All" => "String",
  },
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the Amazon SQS queue whose attributes are set.

    Queue URLs and names are case-sensitive.

  • :attributes (required, Hash<String,String>) —

    A map of attributes to set.

    The following lists the names, descriptions, and values of the special request parameters that the SetQueueAttributes action uses:

    • DelaySeconds – The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 (15 minutes). Default: 0.

    • MaximumMessageSize – The limit of how many bytes a message can contain before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes (1 KiB) up to 1,048,576 bytes (1 MiB). Default: 1,048,576 bytes (1 MiB).

    • MessageRetentionPeriod – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer representing seconds, from 60 (1 minute) to 1,209,600 (14 days). Default: 345,600 (4 days). When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the MessageRetentionPeriod attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the MessageRetentionPeriod is reduced below the age of existing messages.

    • Policy – The queue's policy. A valid Amazon Web Services policy. For more information about policy structure, see Overview of Amazon Web Services IAM Policies in the Identity and Access Management User Guide.

    • ReceiveMessageWaitTimeSeconds – The length of time, in seconds, for which a ReceiveMessage action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.

    • VisibilityTimeout – The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide.

    The following attributes apply only to dead-letter queues:

    • RedrivePolicy – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. The parameters are as follows:

    • deadLetterTargetArn – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of maxReceiveCount is exceeded.

    • maxReceiveCount – The number of times a message is delivered to the source queue before being moved to the dead-letter queue. Default: 10. When the ReceiveCount for a message exceeds the maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.

    • RedriveAllowPolicy – The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:

    • redrivePermission – The permission type that defines which source queues can specify the current queue as the dead-letter queue. Valid values are:

      • allowAll – (Default) Any source queues in this Amazon Web Services account in the same Region can specify this queue as the dead-letter queue.

      • denyAll – No source queues can specify this queue as the dead-letter queue.

      • byQueue – Only queues specified by the sourceQueueArns parameter can specify this queue as the dead-letter queue.

    • sourceQueueArns – The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when the redrivePermission parameter is set to byQueue. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set the redrivePermission parameter to allowAll.

    The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.

    The following attributes apply only to server-side-encryption:

    • KmsMasterKeyId – The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms. While the alias of the AWS-managed CMK for Amazon SQS is always alias/aws/sqs, the alias of a custom CMK can, for example, be alias/MyAlias . For more examples, see KeyId in the Key Management Service API Reference.

    • KmsDataKeyReusePeriodSeconds – The length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt messages before calling KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier. For more information, see How Does the Data Key Reuse Period Work?.

    • SqsManagedSseEnabled – Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS).

    The following attribute applies only to FIFO (first-in-first-out) queues:

    • ContentBasedDeduplication – Enables content-based deduplication. For more information, see Exactly-once processing in the Amazon SQS Developer Guide. Note the following:

    • Every message must have a unique MessageDeduplicationId.

      • You may provide a MessageDeduplicationId explicitly.

      • If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).

      • If you don't provide a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error.

      • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.

    • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.

    • If you send one message with ContentBasedDeduplication enabled and then another message with a MessageDeduplicationId that is the same as the one generated for the first MessageDeduplicationId, the two messages are treated as duplicates and only one copy of the message is delivered.

    The following attributes apply only to high throughput for FIFO queues:

    • DeduplicationScope – Specifies whether message deduplication occurs at the message group or queue level. Valid values are messageGroup and queue.

    • FifoThroughputLimit – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are perQueue and perMessageGroupId. The perMessageGroupId value is allowed only when the value for DeduplicationScope is messageGroup.

    To enable high throughput for FIFO queues, do the following:

    • Set DeduplicationScope to messageGroup.

    • Set FifoThroughputLimit to perMessageGroupId.

    If you set these attributes to anything other than the values shown for enabling high throughput, normal throughput is in effect and deduplication occurs as specified.

    For information on throughput quotas, see Quotas related to messages in the Amazon SQS Developer Guide.

Returns:

  • (Struct) —

    Returns an empty response.

#start_message_move_task(params = {}) ⇒ Types::StartMessageMoveTaskResult

Starts an asynchronous task to move messages from a specified source queue to a specified destination queue.

* This action is currently limited to supporting message redrive from queues that are configured as dead-letter queues (DLQs) of other Amazon SQS queues only. Non-SQS queue sources of dead-letter queues, such as Lambda or Amazon SNS topics, are currently not supported.

  • In dead-letter queues redrive context, the StartMessageMoveTask the source queue is the DLQ, while the destination queue can be the original source queue (from which the messages were driven to the dead-letter-queue), or a custom destination queue.

  • Only one active message movement task is supported per queue at any given time.

Examples:

Request syntax with placeholder values


resp = client.start_message_move_task({
  source_arn: "String", # required
  destination_arn: "String",
  max_number_of_messages_per_second: 1,
})

Response structure


resp.task_handle #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :source_arn (required, String) —

    The ARN of the queue that contains the messages to be moved to another queue. Currently, only ARNs of dead-letter queues (DLQs) whose sources are other Amazon SQS queues are accepted. DLQs whose sources are non-SQS queues, such as Lambda or Amazon SNS topics, are not currently supported.

  • :destination_arn (String) —

    The ARN of the queue that receives the moved messages. You can use this field to specify the destination queue where you would like to redrive messages. If this field is left blank, the messages will be redriven back to their respective original source queues.

  • :max_number_of_messages_per_second (Integer) —

    The number of messages to be moved per second (the message movement rate). You can use this field to define a fixed message movement rate. The maximum value for messages per second is 500. If this field is left blank, the system will optimize the rate based on the queue message backlog size, which may vary throughout the duration of the message movement task.

#tag_queue(params = {}) ⇒ Struct

Add cost allocation tags to the specified Amazon SQS queue. For an overview, see Tagging Your Amazon SQS Queues in the Amazon SQS Developer Guide.

When you use queue tags, keep the following guidelines in mind:

  • Adding more than 50 tags to a queue isn't recommended.

  • Tags don't have any semantic meaning. Amazon SQS interprets tags as character strings.

  • Tags are case-sensitive.

  • A new tag with a key identical to that of an existing tag overwrites the existing tag.

For a full list of tag restrictions, see Quotas related to queues in the Amazon SQS Developer Guide.

Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide.

Examples:

Request syntax with placeholder values


resp = client.tag_queue({
  queue_url: "String", # required
  tags: { # required
    "TagKey" => "TagValue",
  },
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :queue_url (required, String) —

    The URL of the queue.

  • :tags (required, Hash<String,String>) —

    The list of tags to be added to the specified queue.

Returns:

  • (Struct) —

    Returns an empty response.
