Provides Amazon SQS integration for Symfony Messenger.

Available stamps

Symfony\Component\Messenger\Bridge\AmazonSqs\Transport\AmazonSqsFifoStamp
- Use with FIFO queues (queue name ends with .fifo).
- Set per-message "Message group ID" and optional "Message deduplication ID".
- If both FIFO and FairQueue stamps are present, FIFO takes precedence.
Symfony\Component\Messenger\Bridge\AmazonSqs\Transport\AmazonSqsFairQueueStamp
- Enables fair queue processing on standard queues by setting MessageGroupId.
- Use a tenant/group identifier to balance processing across groups.
- Has no effect on FIFO queues. Ignored when FIFO stamp is present.
Symfony\Component\Messenger\Bridge\AmazonSqs\Transport\AmazonSqsXrayTraceHeaderStamp
- Adds an AWS X-Ray TraceId to the outgoing SQS message attributes.
Symfony\Component\Messenger\Bridge\AmazonSqs\Transport\AmazonSqsReceivedStamp
- Carries the SQS ReceiptHandle/message identifier for received messages.

Middleware: Symfony\Component\Messenger\Bridge\AmazonSqs\Middleware\AddFifoStampMiddleware
- If the message implements MessageDeduplicationAwareInterface, the middleware adds AmazonSqsFifoStamp and sets the deduplication ID.
- If the message implements MessageGroupAwareInterface, the middleware sets the group ID on the stamp.
FIFO queues do not support per-message delay. Configure retry strategy with delay: 0.

This package is looking for a backer.
