Timeout value using the ChangeMessageVisibility action.įor example, if the default timeout for a queue is 60 seconds, 15 seconds have elapsed ![]() You can shorten or extend a message's visibility by specifying a new The queue may be insufficient (for example, you might need to process and delete a When you receive a message from a queue and begin to process it, the visibility timeout for If your consumer needs longer than 12 hours, consider using Step Functions.Ĭhanging the visibility timeout for a message However, using a value of 43,195 seconds will work unless there is a significant delay between requesting the message via ReceiveMessage and updating the visibility timeout. For example, if you receive a message and immediately set the 12 hour maximum by sending a ChangeMessageVisibility call with VisibilityTimeout equal to 43,200 seconds, it will likely fail. The maximum visibility timeout is 12 hours from the time that Amazon SQS receives the ReceiveMessage request.Įxtending the visibility timeout does not reset the 12 hour maximum.Īdditionally, you may be unable to set the timeout on an individual message to the full 12 hours (e.g. Process: Specify the initial visibility timeout (for example, 2 minutes) and then-as long as your consumer still works on the message-keepĮxtending the visibility timeout by 2 minutes every minute. If you don't know how long it takes to process a message, create a heartbeat for your consumer For more information, see the best practices in the Processing messages in a timely manner section. Visibility timeout for the returned messages without changing the overall queue When receiving messages, you can also set a special Timeout to the maximum time that it takes your application to process and delete a You canĬhange this setting for the entire queue. Received only once, your consumer should delete it within the duration of theĮvery Amazon SQS queue has the default visibility timeout setting of 30 seconds. Visible to other consumers and the message is received again. ![]() However, if the consumer fails beforeĭeleting the message and your system doesn't call the DeleteMessageĪction for that message before the visibility timeout expires, the message becomes ![]() During this time, theĬonsumer processes and deletes the message. The visibility timeout begins when Amazon SQS returns a message. For additional details see How the Amazon SQS FIFO API Works. This can cause Amazon SQS to include duplicate messages in the same response to a ReceiveMessage operation if the MaxNumberOfMessages If the visibility timeout is 0 seconds, the message must be deleted within the same millisecond it was sent, or it is considered abandoned. When working with FIFO queues, DeleteMessage operations will fail if the request is received outside of the visibility timeout window.
