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
