Feature request: Better failures handling while using both BatchProcessing and LargeMessageHandling about powertools-lambda-java HOT 3 CLOSED

What I am thinking is to give possibility to users to handler specific message exceptions while enriching in some way.

So if during enriching message from S3, if we get an exception, we can probably accept an exception handler class on LargeMessage annotation which users can implement on how they want to deal with the exception.

That way, they can decide themselves, if they would like to throw exception to fail entire batch or would liketo silently deal with the exception and let enriching of other message continue.

Something like:

public class SqsLambdaHandler implements RequestHandler<SQSEvent, String> {

    @Override
    @SqsLargeMessage(enrichFailureHandler = ExceptionHandler.class)
    public String handleRequest(SQSEvent sqsEvent, Context context) {
        return sqsEvent.getRecords().toString();
    }

    class ExceptionHandler implements EnrichFailureHandler {

        @Override
        public void handleFailure(SQSMessage message,
                                  FailedProcessingLargePayloadException e) {
            // Handle exception specific to a message
        }
    }
}

Yeah, I agree. This makes more sense and provides more flexibility.

This will be handled by #797 and #1259
