Subject Semantics of acks=all
Date Fri, 11 Dec 2020 12:20:11 GMT 
Hi,

We have a topic with min.insync.replicas = 2 where each partition is
replicated to 3 nodes.

When we send a produce request with acks=all, the request should fail if
the records don't make it to at least 2 nodes.

If the produce request fails, what does the partition leader do with the
records it has written to the local log. Are they deleted, or will the
producer's retry cause duplication?
