Using the Amazon SQS message deduplication ID

Message deduplication ID is the token used for deduplication of sent messages. If a message with a particular message deduplication ID is sent successfully, any messages sent with the same message deduplication ID are accepted successfully but aren't delivered during the 5-minute deduplication interval.

Note

Amazon SQS continues to keep track of the message deduplication ID even after the message is received and deleted.
