                 Key: KAFKA-14412
                 URL: https://issues.apache.org/jira/browse/KAFKA-14412

          Components: streams
            Reporter: Nicholas Telford

We wish to improve atomicity, consistency and durability of StateStores, especially when operating under EOS.

The changes are outlined in [KIP-892: Transactional Semantics for StateStores|https://cwiki.apache.org/confluence/display/KAFKA/KIP-892%3A+Transactional+Semantics+for+StateStores]

This is an alternative to the opt-in StateStores described in [KIP-844|https://cwiki.apache.org/confluence/display/KAFKA/KIP-844:+Transactional+State+Stores] and KAFKA-12549
