More explicit docs on SQS message acknowledgment?

handle_batch should always return all messages it receives, I will update the docs to make this clear. For changing the ack behaviour on failure, see #17.

Hey Jose, thanks for the quick answer. But you got me even more confused now :)

Say i am processing a batch of 10 messages but i don't like message number 9 for some reason and don't want to ack that one (i.e. want it to go to the error queue after the redrive policy count is reached). How do i proceed in that case? Still return the 10 messages in handle_batch but modify the one that i want failed in some way?

Thanks again!

Ok, my bad. I should mark it as failed: https://hexdocs.pm/broadway/Broadway.Message.html#failed/2

Np! I have added a warning if you happen to return less messages too.
