Overview

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

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

For details on configuring region and credentials see the [developer guide](/sdk-for-ruby/v3/developer-guide/setup-config.html).

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

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

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

    Your AWS credentials. This can be an 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`

    • The ‘:access_key_id`, `:secret_access_key`, and `:session_token` options.

    • ENV, ENV

    • ‘~/.aws/credentials`

    • ‘~/.aws/config`

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of ‘Aws::InstanceProfileCredentails` or `Aws::ECSCredentials` to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV to true.

  • :region (required, String) —

#add_layer_version_permission(params = {}) ⇒ Types::AddLayerVersionPermissionResponse

Adds permissions to the resource-based policy of a version of an [Lambda layer]. Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all accounts in an organization, or all Amazon Web Services accounts.

To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :layer_name (required, String) —

    The name or Amazon Resource Name (ARN) of the layer.

  • :version_number (required, Integer) —

    The version number.

  • :statement_id (required, String) —

    An identifier that distinguishes the policy from others on the same layer version.

  • :action (required, String) —

    The API action that grants access to the layer. For example, ‘lambda:GetLayerVersion`.

  • :principal (required, String) —

    An account ID, or ‘*` to grant layer usage permission to all accounts in an organization, or all Amazon Web Services accounts (if `organizationId` is not specified). For the last case, make sure that you really do want all Amazon Web Services accounts to have usage permission to this layer.

  • :organization_id (String) —

    With the principal set to ‘*`, grant permission to all accounts in the specified organization.

  • :revision_id (String) —

    Only update the policy if the revision ID matches the ID specified. Use this option to avoid modifying a policy that has changed since you last read it.

end

#add_permission(params = {}) ⇒ Types::AddPermissionResponse

Grants an Amazon Web Service, Amazon Web Services account, or Amazon Web Services organization permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function. Note: Lambda does not support adding policies to version $LATEST.

To grant permission to another account, specify the account ID as the ‘Principal`. To grant permission to an organization defined in Organizations, specify the organization ID as the `PrincipalOrgID`. For Amazon Web Services, the principal is a domain-style identifier that the service defines, such as `s3.amazonaws.com` or `sns.amazonaws.com`. For Amazon Web Services, you can also specify the ARN of the associated resource as the `SourceArn`. If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function.

This operation adds a statement to a resource-based permissions policy for the function. For more information about function policies, see [Using resource-based policies for Lambda].

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name of the Lambda function, version, or alias.

    **Name formats**

    • **Function name** – ‘my-function` (name-only), `my-function:v1` (with alias).

    • **Function ARN** – ‘arn:aws:lambda:us-west-2:123456789012:function:my-function`.

    • **Partial ARN** – ‘123456789012:function:my-function`.

    You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :statement_id (required, String) —

    A statement identifier that differentiates the statement from others in the same policy.

  • :action (required, String) —

    The action that the principal can use on the function. For example, ‘lambda:InvokeFunction` or `lambda:GetFunction`.

  • :principal (required, String) —

    The Amazon Web Service or Amazon Web Services account that invokes the function. If you specify a service, use ‘SourceArn` or `SourceAccount` to limit who can invoke the function through that service.

  • :source_arn (String) —

    For Amazon Web Services, the ARN of the Amazon Web Services resource that invokes the function. For example, an Amazon S3 bucket or Amazon SNS topic.

    Note that Lambda configures the comparison using the ‘StringLike` operator.

  • :source_account (String) —

    For Amazon Web Service, the ID of the Amazon Web Services account that owns the resource. Use this together with ‘SourceArn` to ensure that the specified account owns the resource. It is possible for an Amazon S3 bucket to be deleted by its owner and recreated by another account.

  • :event_source_token (String) —

    For Alexa Smart Home functions, a token that the invoker must supply.

  • :qualifier (String) —

    Specify a version or alias to add permissions to a published version of the function.

  • :revision_id (String) —

    Update the policy only if the revision ID matches the ID that’s specified. Use this option to avoid modifying a policy that has changed since you last read it.

  • :principal_org_id (String) —

    The identifier for your organization in Organizations. Use this to grant permissions to all the Amazon Web Services accounts under this organization.

  • :function_url_auth_type (String) —

    The type of authentication that your function URL uses. Set to ‘AWS_IAM` if you want to restrict access to authenticated users only. Set to `NONE` if you want to bypass IAM authentication to create a public endpoint. For more information, see [Security and auth model for Lambda function URLs].

#create_event_source_mapping(params = {}) ⇒ Types::EventSourceMappingConfiguration

Creates a mapping between an event source and an Lambda function. Lambda reads items from the event source and invokes the function.

For details about how to configure different event sources, see the following topics.

  • Amazon DynamoDB Streams][1
  • Amazon Kinesis][2
  • Amazon SQS][3
  • Amazon MQ and RabbitMQ][4
  • Amazon MSK][5
  • Apache Kafka][6
  • Amazon DocumentDB][7

The following error handling options are available only for stream sources (DynamoDB and Kinesis):

  • ‘BisectBatchOnFunctionError` – If the function returns an error, split the batch in two and retry.

  • ‘DestinationConfig` – Send discarded records to an Amazon SQS queue or Amazon SNS topic.

  • ‘MaximumRecordAgeInSeconds` – Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires

  • ‘MaximumRetryAttempts` – Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

  • ‘ParallelizationFactor` – Process multiple batches from each shard concurrently.

For information about which configuration parameters apply to each event source, see the following topics.

  • Amazon DynamoDB Streams][8
  • Amazon Kinesis][9
  • Amazon SQS][10
  • Amazon MQ and RabbitMQ][11
  • Amazon MSK][12

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :event_source_arn (String) —

    The Amazon Resource Name (ARN) of the event source.

    • **Amazon Kinesis** – The ARN of the data stream or a stream consumer.

    • **Amazon DynamoDB Streams** – The ARN of the stream.

    • **Amazon Simple Queue Service** – The ARN of the queue.

    • **Amazon Managed Streaming for Apache Kafka** – The ARN of the cluster.

    • **Amazon MQ** – The ARN of the broker.

    • **Amazon DocumentDB** – The ARN of the DocumentDB change stream.

  • :function_name (required, String) —

    The name of the Lambda function.

    **Name formats**

    • **Function name** – ‘MyFunction`.

    • **Function ARN** – ‘arn:aws:lambda:us-west-2:123456789012:function:MyFunction`.

    • **Version or Alias ARN** – ‘arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD`.

    • **Partial ARN** – ‘123456789012:function:MyFunction`.

    The length constraint applies only to the full ARN. If you specify only the function name, it’s limited to 64 characters in length.

  • :enabled (Boolean) —

    When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

    Default: True

  • :batch_size (Integer) —

    The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

    • **Amazon Kinesis** – Default 100. Max 10,000.

    • **Amazon DynamoDB Streams** – Default 100. Max 10,000.

    • **Amazon Simple Queue Service** – Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.

    • **Amazon Managed Streaming for Apache Kafka** – Default 100. Max 10,000.

    • **Self-managed Apache Kafka** – Default 100. Max 10,000.

    • **Amazon MQ (ActiveMQ and RabbitMQ)** – Default 100. Max 10,000.

    • DocumentDB – Default 100. Max 10,000.

  • :filter_criteria (Types::FilterCriteria) —

    An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see [Lambda event filtering].

    [1]: docs.aws.amazon.com/lambda/latest/dg/invocation-eventfiltering.html

  • :maximum_batching_window_in_seconds (Integer) —

    The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure ‘MaximumBatchingWindowInSeconds` to any value from 0 seconds to 300 seconds in increments of seconds.

    For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change ‘MaximumBatchingWindowInSeconds` in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

    Related setting: For streams and Amazon SQS event sources, when you set ‘BatchSize` to a value greater than 10, you must set `MaximumBatchingWindowInSeconds` to at least 1.

  • :parallelization_factor (Integer) — default: Kinesis and DynamoDB Streams only —

    The number of batches to process from each shard concurrently.

  • :starting_position (String) —

    The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK Streams sources. ‘AT_TIMESTAMP` is supported only for Amazon Kinesis streams and Amazon DocumentDB.

  • :starting_position_timestamp (Time, DateTime, Date, Integer, String) —

    With ‘StartingPosition` set to `AT_TIMESTAMP`, the time from which to start reading.

  • :destination_config (Types::DestinationConfig) — default: Kinesis and DynamoDB Streams only —

    A standard Amazon SQS queue or standard Amazon SNS topic destination for discarded records.

  • :maximum_record_age_in_seconds (Integer) — default: Kinesis and DynamoDB Streams only —

    Discard records older than the specified age. The default value is infinite (-1).

  • :bisect_batch_on_function_error (Boolean) — default: Kinesis and DynamoDB Streams only —

    If the function returns an error, split the batch in two and retry.

  • :maximum_retry_attempts (Integer) — default: Kinesis and DynamoDB Streams only —

    Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

  • :tumbling_window_in_seconds (Integer) — default: Kinesis and DynamoDB Streams only —

    The duration in seconds of a processing window for DynamoDB and Kinesis Streams event sources. A value of 0 seconds indicates no tumbling window.

  • :topics (Array<String>) —

    The name of the Kafka topic.

  • :queues (Array<String>) — default: MQ —

    The name of the Amazon MQ broker destination queue to consume.

  • :source_access_configurations (Array<Types::SourceAccessConfiguration>) —

    An array of authentication protocols or VPC components required to secure your event source.

  • :self_managed_event_source (Types::SelfManagedEventSource) —

    The self-managed Apache Kafka cluster to receive records from.

  • :function_response_types (Array<String>) — default: Kinesis, DynamoDB Streams, and Amazon SQS —

    A list of current response type enums applied to the event source mapping.

  • :amazon_managed_kafka_event_source_config (Types::AmazonManagedKafkaEventSourceConfig) —

  • :scaling_config (Types::ScalingConfig) — default: Amazon SQS only —

    The scaling configuration for the event source. For more information, see [Configuring maximum concurrency for Amazon SQS event sources].

    [1]: docs.aws.amazon.com/lambda/latest/dg/with-sqs.html#events-sqs-max-concurrency

  • :document_db_event_source_config (Types::DocumentDBEventSourceConfig) —

    Specific configuration settings for a DocumentDB event source.

#create_function(params = {}) ⇒ Types::FunctionConfiguration

Creates a Lambda function. To create a function, you need a

deployment package][1

and an [execution role]. The deployment

package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.

If the deployment package is a [container image], then you set the package type to ‘Image`. For a container image, the code property must include the URI of a container image in the Amazon ECR registry. You do not need to specify the handler and runtime properties.

If the deployment package is a [.zip file archive], then you set the package type to ‘Zip`. For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties. The code in the deployment package must be compatible with the target instruction set architecture of the function (`x86-64` or `arm64`). If you do not specify the architecture, then the default value is `x86-64`.

When you create a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute or so. During this time, you can’t invoke or modify the function. The ‘State`, `StateReason`, and `StateReasonCode` fields in the response from GetFunctionConfiguration indicate when the function is ready to invoke. For more information, see [Lambda function states].

A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function’s code and configuration. A published version is a snapshot of your function code and configuration that can’t be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the ‘Publish` parameter to create version `1` of your function from its initial configuration.

The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags (TagResource) and per-function concurrency limits (PutFunctionConcurrency).

You can use code signing if your deployment package is a .zip file archive. To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with UpdateFunctionCode, Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set of signing profiles, which define the trusted publishers for this function.

If another Amazon Web Services account or an Amazon Web Service invokes your function, use AddPermission to grant permission by creating a resource-based Identity and Access Management (IAM) policy. You can grant permissions at the function level, on a version, or on an alias.

To invoke your function directly, use Invoke. To invoke your function in response to events in other Amazon Web Services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see [Invoking Lambda functions].

#delete_function(params = {}) ⇒ Struct

Deletes a Lambda function. To delete a specific function version, use the ‘Qualifier` parameter. Otherwise, all versions and aliases are deleted.

To delete Lambda event source mappings that invoke a function, use DeleteEventSourceMapping. For Amazon Web Services and resources that invoke your function directly, delete the trigger in the service where you originally configured it.

Examples:

Request syntax with placeholder values


resp = client.delete_function({
  function_name: "FunctionName", # required
  qualifier: "Qualifier",
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name of the Lambda function or version.

    **Name formats**

    • **Function name** – ‘my-function` (name-only), `my-function:1` (with version).

    • **Function ARN** – ‘arn:aws:lambda:us-west-2:123456789012:function:my-function`.

    • **Partial ARN** – ‘123456789012:function:my-function`.

    You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :qualifier (String) —

    Specify a version to delete. You can’t delete a version that an alias references.

Returns:

  • (Struct) —

    Returns an empty response.

#invoke(params = {}) ⇒ Types::InvocationResponse

Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set ‘InvocationType` to `Event`.

For [synchronous invocation], details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the

execution log][2

and [trace].

When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see [Error handling and automatic retries in Lambda].

For [asynchronous invocation], Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a [dead-letter queue].

The status code in the API response doesn’t reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, [quota] errors, or issues with your function’s code and configuration. For example, Lambda returns ‘TooManyRequestsException` if running the function would cause you to exceed a concurrency limit at either the account level (`ConcurrentInvocationLimitExceeded`) or function level (`ReservedFunctionConcurrentInvocationLimitExceeded`).

For functions with a long timeout, your client might disconnect during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.

This operation requires permission for the [lambda:InvokeFunction] action. For details on how to set up permissions for cross-account invocations, see [Granting function access to other accounts].

#invoke_with_response_stream(params = {}) ⇒ Types::InvokeWithResponseStreamResponse

Configure your Lambda functions to stream response payloads back to clients. For more information, see [Configuring a Lambda function to stream responses].

[1]: docs.aws.amazon.com/lambda/latest/dg/configuration-response-streaming.html

Examples:

EventStream Operation Example


You can process event once it arrives immediately, or wait until
full response complete and iterate through eventstream enumerator.

To interact with event immediately, you need to register #invoke_with_response_stream
with callbacks, callbacks can be register for specifc events or for all events,
callback for errors in the event stream is also available for register.

Callbacks can be passed in by `:event_stream_handler` option or within block
statement attached to #invoke_with_response_stream call directly. Hybrid pattern of both
is also supported.

`:event_stream_handler` option takes in either Proc object or
Aws::Lambda::EventStreams::InvokeWithResponseStreamResponseEvent object.

Usage pattern a): callbacks with a block attached to #invoke_with_response_stream
  Example for registering callbacks for all event types and error event

  client.invoke_with_response_stream( # params input# ) do |stream|
    stream.on_error_event do |event|
      # catch unmodeled error event in the stream
      raise event
      # => Aws::Errors::EventError
      # event.event_type => :error
      # event.error_code => String
      # event.error_message => String
    end

    stream.on_event do |event|
      # process all events arrive
      puts event.event_type
      ...
    end

  end

Usage pattern b): pass in `:event_stream_handler` for #invoke_with_response_stream

  1) create a Aws::Lambda::EventStreams::InvokeWithResponseStreamResponseEvent object
  Example for registering callbacks with specific events

    handler = Aws::Lambda::EventStreams::InvokeWithResponseStreamResponseEvent.new
    handler.on_payload_chunk_event do |event|
      event # => Aws::Lambda::Types::PayloadChunk
    end
    handler.on_invoke_complete_event do |event|
      event # => Aws::Lambda::Types::InvokeComplete
    end

  client.invoke_with_response_stream( # params input #, event_stream_handler: handler)

  2) use a Ruby Proc object
  Example for registering callbacks with specific events

  handler = Proc.new do |stream|
    stream.on_payload_chunk_event do |event|
      event # => Aws::Lambda::Types::PayloadChunk
    end
    stream.on_invoke_complete_event do |event|
      event # => Aws::Lambda::Types::InvokeComplete
    end
  end

  client.invoke_with_response_stream( # params input #, event_stream_handler: handler)

Usage pattern c): hybird pattern of a) and b)

    handler = Aws::Lambda::EventStreams::InvokeWithResponseStreamResponseEvent.new
    handler.on_payload_chunk_event do |event|
      event # => Aws::Lambda::Types::PayloadChunk
    end
    handler.on_invoke_complete_event do |event|
      event # => Aws::Lambda::Types::InvokeComplete
    end

  client.invoke_with_response_stream( # params input #, event_stream_handler: handler) do |stream|
    stream.on_error_event do |event|
      # catch unmodeled error event in the stream
      raise event
      # => Aws::Errors::EventError
      # event.event_type => :error
      # event.error_code => String
      # event.error_message => String
    end
  end

Besides above usage patterns for process events when they arrive immediately, you can also
iterate through events after response complete.

Events are available at resp.event_stream # => Enumerator
For parameter input example, please refer to following request syntax

Request syntax with placeholder values


resp = client.invoke_with_response_stream({
  function_name: "NamespacedFunctionName", # required

    • ‘DryRun` – Validate parameter values and verify that the IAM user or role has permission to invoke the function.

  • :log_type (String) —

    Set to ‘Tail` to include the execution log in the response. Applies to synchronously invoked functions only.

  • :client_context (String) —

    Up to 3,583 bytes of base64-encoded data about the invoking client to pass to the function in the context object.

  • :qualifier (String) —

    The alias name.

#publish_version(params = {}) ⇒ Types::FunctionConfiguration

Creates a [version] from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn’t change.

Lambda doesn’t publish a version if the function’s configuration and code haven’t changed since the last version. Use UpdateFunctionCode or UpdateFunctionConfiguration to update the function before publishing a version.

Clients can invoke versions directly or with an alias. To create an alias, use CreateAlias.

#put_function_concurrency(params = {}) ⇒ Types::Concurrency

Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.

Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.

Use GetAccountSettings to see your Regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren’t configured with a per-function limit. For more information, see [Lambda function scaling].

#put_function_event_invoke_config(params = {}) ⇒ Types::FunctionEventInvokeConfig

Configures options for [asynchronous invocation] on a function, version, or alias. If a configuration already exists for a function, version, or alias, this operation overwrites it. If you exclude any settings, they are removed. To set one option without affecting existing settings for other options, use UpdateFunctionEventInvokeConfig.

By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration.

To send an invocation record to a queue, topic, function, or event bus, specify a [destination]. You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :qualifier (String) —

    Specify a version of the function. This can be ‘$LATEST` or a published version number. If no value is specified, the configuration for the `$LATEST` version is returned.

  • :update_runtime_on (required, String) —

    Specify the runtime update mode.

    • **Auto (default)** - Automatically update to the most recent and secure runtime version using a [Two-phase runtime version rollout]. This is the best choice for most customers to ensure they always benefit from runtime updates.

    • **Function update** - Lambda updates the runtime of your function to the most recent and secure runtime version when you update your function. This approach synchronizes runtime updates with function deployments, giving you control over when runtime updates are applied and allowing you to detect and mitigate rare runtime update incompatibilities early. When using this setting, you need to regularly update your functions to keep their runtime up-to-date.

    • Manual - You specify a runtime version in your function configuration. The function will use this runtime version indefinitely. In the rare case where a new runtime version is incompatible with an existing function, this allows you to roll back your function to an earlier runtime version. For more information, see [Roll back a runtime version].

    [1]: docs.aws.amazon.com/lambda/latest/dg/runtimes-update.html#runtime-management-two-phase [2]: docs.aws.amazon.com/lambda/latest/dg/runtimes-update.html#runtime-management-rollback

  • :runtime_version_arn (String) —

    The ARN of the runtime version you want the function to use.

    <note markdown=“1”> This is only required if you’re using the Manual runtime update mode.

#update_event_source_mapping(params = {}) ⇒ Types::EventSourceMappingConfiguration

Updates an event source mapping. You can change the function that Lambda invokes, or pause invocation and resume later from the same location.

For details about how to configure different event sources, see the following topics.

  • Amazon DynamoDB Streams][1
  • Amazon Kinesis][2
  • Amazon SQS][3
  • Amazon MQ and RabbitMQ][4
  • Amazon MSK][5
  • Apache Kafka][6
  • Amazon DocumentDB][7

The following error handling options are available only for stream sources (DynamoDB and Kinesis):

  • ‘BisectBatchOnFunctionError` – If the function returns an error, split the batch in two and retry.

  • ‘DestinationConfig` – Send discarded records to an Amazon SQS queue or Amazon SNS topic.

  • ‘MaximumRecordAgeInSeconds` – Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires

  • ‘MaximumRetryAttempts` – Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

  • ‘ParallelizationFactor` – Process multiple batches from each shard concurrently.

For information about which configuration parameters apply to each event source, see the following topics.

  • Amazon DynamoDB Streams][8
  • Amazon Kinesis][9
  • Amazon SQS][10
  • Amazon MQ and RabbitMQ][11
  • Amazon MSK][12

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :uuid (required, String) —

    The identifier of the event source mapping.

  • :function_name (String) —

    The name of the Lambda function.

    **Name formats**

    • **Function name** – ‘MyFunction`.

    • **Function ARN** – ‘arn:aws:lambda:us-west-2:123456789012:function:MyFunction`.

    • **Version or Alias ARN** – ‘arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD`.

    • **Partial ARN** – ‘123456789012:function:MyFunction`.

    The length constraint applies only to the full ARN. If you specify only the function name, it’s limited to 64 characters in length.

  • :enabled (Boolean) —

    When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

    Default: True

  • :batch_size (Integer) —

    The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

    • **Amazon Kinesis** – Default 100. Max 10,000.

    • **Amazon DynamoDB Streams** – Default 100. Max 10,000.

    • **Amazon Simple Queue Service** – Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.

    • **Amazon Managed Streaming for Apache Kafka** – Default 100. Max 10,000.

    • **Self-managed Apache Kafka** – Default 100. Max 10,000.

    • **Amazon MQ (ActiveMQ and RabbitMQ)** – Default 100. Max 10,000.

    • DocumentDB – Default 100. Max 10,000.

  • :filter_criteria (Types::FilterCriteria) —

    An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see [Lambda event filtering].

    [1]: docs.aws.amazon.com/lambda/latest/dg/invocation-eventfiltering.html

  • :maximum_batching_window_in_seconds (Integer) —

    The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure ‘MaximumBatchingWindowInSeconds` to any value from 0 seconds to 300 seconds in increments of seconds.

    For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change ‘MaximumBatchingWindowInSeconds` in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

    Related setting: For streams and Amazon SQS event sources, when you set ‘BatchSize` to a value greater than 10, you must set `MaximumBatchingWindowInSeconds` to at least 1.

  • :destination_config (Types::DestinationConfig) — default: Kinesis and DynamoDB Streams only —

    A standard Amazon SQS queue or standard Amazon SNS topic destination for discarded records.

  • :maximum_record_age_in_seconds (Integer) — default: Kinesis and DynamoDB Streams only —

    Discard records older than the specified age. The default value is infinite (-1).

  • :bisect_batch_on_function_error (Boolean) — default: Kinesis and DynamoDB Streams only —

    If the function returns an error, split the batch in two and retry.

  • :maximum_retry_attempts (Integer) — default: Kinesis and DynamoDB Streams only —

    Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

  • :parallelization_factor (Integer) — default: Kinesis and DynamoDB Streams only —

    The number of batches to process from each shard concurrently.

  • :source_access_configurations (Array<Types::SourceAccessConfiguration>) —

    An array of authentication protocols or VPC components required to secure your event source.

  • :tumbling_window_in_seconds (Integer) — default: Kinesis and DynamoDB Streams only —

    The duration in seconds of a processing window for DynamoDB and Kinesis Streams event sources. A value of 0 seconds indicates no tumbling window.

  • :function_response_types (Array<String>) — default: Kinesis, DynamoDB Streams, and Amazon SQS —

    A list of current response type enums applied to the event source mapping.

  • :scaling_config (Types::ScalingConfig) — default: Amazon SQS only —

    The scaling configuration for the event source. For more information, see [Configuring maximum concurrency for Amazon SQS event sources].

    [1]: docs.aws.amazon.com/lambda/latest/dg/with-sqs.html#events-sqs-max-concurrency

#update_function_code(params = {}) ⇒ Types::FunctionConfiguration

Updates a Lambda function’s code. If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see [Configuring code signing for Lambda].

If the function’s package type is ‘Image`, then you must specify the code package in `ImageUri` as the URI of a [container image] in the Amazon ECR registry.

If the function’s package type is ‘Zip`, then you must specify the deployment package as a [.zip file archive]. Enter the Amazon S3 bucket and key of the code .zip file location. You can also provide the function code inline using the `ZipFile` field.

The code in the deployment package must be compatible with the target instruction set architecture of the function (‘x86-64` or `arm64`).

The function’s code is locked when you publish a version. You can’t modify the code of a published version, only the unpublished version.

<note markdown=“1”> For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name of the Lambda function.

    **Name formats**

    • **Function name** – ‘my-function`.

    • **Function ARN** – ‘arn:aws:lambda:us-west-2:123456789012:function:my-function`.

    • **Partial ARN** – ‘123456789012:function:my-function`.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :zip_file (String, StringIO, File) —

    The base64-encoded contents of the deployment package. Amazon Web Services SDK and CLI clients handle the encoding for you. Use only with a function defined with a .zip file archive deployment package.

  • :s3_bucket (String) —

    An Amazon S3 bucket in the same Amazon Web Services Region as your function. The bucket can be in a different Amazon Web Services account. Use only with a function defined with a .zip file archive deployment package.

  • :s3_key (String) —

    The Amazon S3 key of the deployment package. Use only with a function defined with a .zip file archive deployment package.

  • :s3_object_version (String) —

    For versioned objects, the version of the deployment package object to use.

  • :image_uri (String) —

    URI of a container image in the Amazon ECR registry. Do not use for a function defined with a .zip file archive.

  • :publish (Boolean) —

    Set to true to publish a new version of the function after updating the code. This has the same effect as calling PublishVersion separately.

  • :dry_run (Boolean) —

    Set to true to validate the request parameters and access permissions without modifying the function code.

  • :revision_id (String) —

    Update the function only if the revision ID matches the ID that’s specified. Use this option to avoid modifying a function that has changed since you last read it.

  • :architectures (Array<String>) —

    The instruction set architecture that the function supports. Enter a string array with one of the valid values (arm64 or x86_64). The default value is ‘x86_64`.

Returns:

#update_function_configuration(params = {}) ⇒ Types::FunctionConfiguration

Modify the version-specific settings of a Lambda function.

When you update a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute. During this time, you can’t modify the function, but you can still invoke it. The ‘LastUpdateStatus`, `LastUpdateStatusReason`, and `LastUpdateStatusReasonCode` fields in the response from GetFunctionConfiguration indicate when the update is complete and the function is processing events with the new configuration. For more information, see [Lambda function states].

These settings can vary between versions of a function and are locked when you publish a version. You can’t modify the configuration of a published version, only the unpublished version.

To configure function concurrency, use PutFunctionConcurrency. To grant invoke permissions to an Amazon Web Services account or Amazon Web Service, use AddPermission.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name of the Lambda function.

    **Name formats**

    • **Function name** – ‘my-function`.

    • **Function ARN** – ‘arn:aws:lambda:us-west-2:123456789012:function:my-function`.

    • **Partial ARN** – ‘123456789012:function:my-function`.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :qualifier (String) —

    The alias name.

  • :auth_type (String) —

    The type of authentication that your function URL uses. Set to ‘AWS_IAM` if you want to restrict access to authenticated users only. Set to `NONE` if you want to bypass IAM authentication to create a public endpoint. For more information, see [Security and auth model for Lambda function URLs].

    [1]: docs.aws.amazon.com/lambda/latest/dg/urls-auth.html

  • :cors (Types::Cors) —

    The [cross-origin resource sharing (CORS)] settings for your function URL.

    [1]: developer.mozilla.org/en-US/docs/Web/HTTP/CORS

  • :invoke_mode (String) —

    Use one of the following options:

    • ‘BUFFERED` – This is the default option. Lambda invokes your function using the `Invoke` API operation. Invocation results are available when the payload is complete. The maximum payload size is 6 MB.

    • ‘RESPONSE_STREAM` – Your function streams payload results as they become available. Lambda invokes your function using the `InvokeWithResponseStream` API operation. The maximum response payload size is 20 MB, however, you can [request a quota increase].

end

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean

Polls an API operation until a resource enters a desired state.

## Basic Usage

A waiter will call an API operation until:

  • It is successful

  • It enters a terminal state

  • It makes the maximum number of attempts

In between attempts, the waiter will sleep.

# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.

# poll for ~25 seconds
client.wait_until(waiter_name, params, {
  max_attempts: 5,
  delay: 5,
})

## Callbacks

You can be notified before each polling attempt and before each delay. If you throw ‘:success` or `:failure` from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(waiter_name, params, {

  # disable max attempts
  max_attempts: nil,

  # poll for 1 hour, instead of a number of attempts
  before_wait: -> (attempts, response) do
    throw :failure if Time.now - started_at > 3600
  end
})

## Handling Errors

When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

## Valid Waiters

The following table lists the valid waiter names, the operations they call, and the default ‘:delay` and `:max_attempts` values.

| waiter_name | params | :delay | :max_attempts | | ———————— | ———————————– | ——– | ————- | | function_active | #get_function_configuration | 5 | 60 | | function_active_v2 | #get_function | 1 | 300 | | function_exists | #get_function | 1 | 20 | | function_updated | #get_function_configuration | 5 | 60 | | function_updated_v2 | #get_function | 1 | 300 | | published_version_active | #get_function_configuration | 5 | 312 |

Parameters:

  • waiter_name (Symbol)
  • params (Hash) (defaults to: {}) —

    ({})

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :max_attempts (Integer)
  • :delay (Integer)
  • :before_attempt (Proc)
  • :before_wait (Proc)

Yields:

  • (w.waiter)

Returns:

  • (Boolean) —

    Returns ‘true` if the waiter was successful.

Raises:

  • (Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError) —

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError) —

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError) —

    Raised when you request to wait for an unknown state.
