Subject delivery semantics?
Date Fri, 30 Mar 2018 15:02:46 GMT
Can someone clarify it:
- "At most once": messages may be lost but are never redelivered
Does it mean: "commit, when message is received by leader partition,
retries disabled for producer no matter of ISR status"?
- "At least once": commit only when message is ackd by all partitions in
replication set, if not - keep retrying by producer"?

- "Exactly once - each message is delivered only once"... What does that
mean? Delivered to leader partition and never replicated?

Thank you,
V
