Bytes Based batching for SendMessageRequest Batching

Motivation and Context

Reference Doc for size of SendMessageBatch Size

https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_SendMessageBatch.html

The maximum allowed individual message size and the maximum total payload size (the sum of the individual lengths of all of the batched messages) are both 256 KiB (262,144 bytes).

Reference Doc for size of message-attributes

https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-message-metadata.html#sqs-message-attributes In our implementation, we’ve accounted for an ATTRIBUTE_MAPS_PAYLOAD_BYTES size of 16 KB. This represents a worst-case scenario where the user sends the maximum possible attribute map in SendMessage. This consideration primarily affects batching in cases where the messages payload comes close to 240 KB. For smaller messages, this will have little to no impact on batching behavior.
