#create(options = {}) ⇒ EventSubscription

Examples:

Request syntax with placeholder values


eventsubscription = event_subscription.create({
  sns_topic_arn: "String", # required
  source_type: "String",
  event_categories: ["String"],
  source_ids: ["String"],
  enabled: false,
  tags: [
    {
      key: "String",
      value: "String",
    },
  ],
})

Parameters:

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

    ({})

Options Hash (options):

  • :sns_topic_arn (required, String) —

    The Amazon Resource Name (ARN) of the SNS topic created for event notification. SNS automatically creates the ARN when you create a topic and subscribe to it.

    <note markdown=“1”> RDS doesn’t support FIFO (first in, first out) topics. For more information, see [Message ordering and deduplication (FIFO topics)] in the *Amazon Simple Notification Service Developer Guide*.

    </note>

    [1]: docs.aws.amazon.com/sns/latest/dg/sns-fifo-topics.html

  • :source_type (String) —

    The type of source that is generating the events. For example, if you want to be notified of events generated by a DB instance, you set this parameter to ‘db-instance`. For RDS Proxy events, specify `db-proxy`. If this value isn’t specified, all events are returned.

    Valid Values:‘ db-instance | db-cluster | db-parameter-group | db-security-group | db-snapshot | db-cluster-snapshot | db-proxy | zero-etl | custom-engine-version | blue-green-deployment `

  • :event_categories (Array<String>) —

    A list of event categories for a particular source type (‘SourceType`) that you want to subscribe to. You can see a list of the categories for a given source type in the “Amazon RDS event categories and event messages” section of the [ *Amazon RDS User Guide* ][1] or the [ *Amazon Aurora User Guide* ][2]. You can also see this list by using the `DescribeEventCategories` operation.

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Events.Messages.html [2]: docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_Events.Messages.html

  • :source_ids (Array<String>) —

    The list of identifiers of the event sources for which events are returned. If not specified, then all sources are included in the response. An identifier must begin with a letter and must contain only ASCII letters, digits, and hyphens. It can’t end with a hyphen or contain two consecutive hyphens.

    Constraints:

    • If ‘SourceIds` are supplied, `SourceType` must also be provided.

    • If the source type is a DB instance, a ‘DBInstanceIdentifier` value must be supplied.

    • If the source type is a DB cluster, a ‘DBClusterIdentifier` value must be supplied.

    • If the source type is a DB parameter group, a ‘DBParameterGroupName` value must be supplied.

    • If the source type is a DB security group, a ‘DBSecurityGroupName` value must be supplied.

    • If the source type is a DB snapshot, a ‘DBSnapshotIdentifier` value must be supplied.

    • If the source type is a DB cluster snapshot, a ‘DBClusterSnapshotIdentifier` value must be supplied.

    • If the source type is an RDS Proxy, a ‘DBProxyName` value must be supplied.

  • :enabled (Boolean) —

    Specifies whether to activate the subscription. If the event notification subscription isn’t activated, the subscription is created but not active.

  • :tags (Array<Types::Tag>) —

    A list of tags. For more information, see [Tagging Amazon RDS Resources] in the *Amazon RDS User Guide.*

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::RDS::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

## Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

## Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

## 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
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

## Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

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

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

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

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

    Delay between each

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Yield Parameters:

  • resource (Resource) —

    to be used in the waiting condition.

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

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

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —

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

  • (NotImplementedError) —

    Raised when the resource does not
