  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.

    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.

  • :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 or the Amazon Aurora User Guide . You can also see this list by using the DescribeEventCategories operation.

  • :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 or Tagging Amazon Aurora and Amazon RDS resources in the Amazon Aurora 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
