[Feature Request]: Support strict batch timeouts for AWS SQS batch writes

[mosche]

What would you like to happen?

Timeouts of SQS batches are checked on arrival of new messages.
In cases where this causes too much delay (short timeouts, irregular/low frequency of messages), strict enforcement of batch timeouts should be done using a separate scheduler thread.
