If you give the same MessageGroupId, then two message will be handled by the same shared in order. The name has to be `<name>.fifo`, if you don't end with `.fifo`, it will not be a FIFO queue. SQS FIFO - Deduplication
Message attributes copy. Support for FIFO queues. MessageGroupId and MessageDeduplicationId are copied over to the destination messages. An optional flag to limit the number of messages to move. Installing SQS Mover is pre-compiled for macOS, Linux, Windows and does not require additional dependenc...
