Kaushik Raina updated KAFKA-18579:
----------------------------------
Description:
* In
[KIP-890|https://cwiki.apache.org/confluence/display/KAFKA/KIP-890%3A+Transactions+Server-Side+Defense]
we introduced `TransactionAbortableException`. Transaction producer can throw
both `TimeoutException` or `TransactionAbortableException`.
* Applications using should handle TimeoutException from transaction producer
as abortable because it’s not safe to retry the produce. Retrying would assign
new sequence numbers to the messages, and if the original message had actually
succeeded, the new messages would become duplicates, breaking exactly-once
semantics. Details:
