/AWS1/CL_SQS=>STARTMESSAGEMOVETASK()¶
About StartMessageMoveTask¶
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
StartMessageMoveTaskthe 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. -
Currently, only standard queues support redrive. FIFO queues don't support redrive.
-
Only one active message movement task is supported per queue at any given time.
Method Signature¶
IMPORTING¶
Required arguments:¶
IV_SOURCEARN TYPE /AWS1/SQSSTRING /AWS1/SQSSTRING¶
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.
Optional arguments:¶
IV_DESTINATIONARN TYPE /AWS1/SQSSTRING /AWS1/SQSSTRING¶
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.
IV_MAXNUMBEROFMESSAGESPERSEC TYPE /AWS1/SQSNULLABLEINTEGER /AWS1/SQSNULLABLEINTEGER¶
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.
