Feature request: Support Sequential Async Processing of Records for SqsFifoPartialProcessor

[amaral-ng]

Use case

I am working with a FIFO SQS queue that requires processing batch records in an asynchronous manner. However, to maintain the order of messages, the SqsFifoPartialProcessor currently only supports sequential synchronous processing. This limitation prevents me from using asynchronous processing in my FIFO queue handler, which is essential for my use case.

Solution/User Experience

I propose enhancing the SqsFifoPartialProcessor to support sequential asynchronous processing while maintaining message ordering. This approach would be similar to the solution implemented here, but tailored to work with the SqsFifoPartialProcessor. This would allow users to leverage asynchronous processing within FIFO queues without sacrificing the ordering guarantees.
