Semantics of acks=all
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?

Hi,
the record is not committed to the filesystem and an error is returned to the producer.
