------------------------------------

             Summary: Improve KTable Source state store auto-generated names
                 Key: KAFKA-6274
                 URL: https://issues.apache.org/jira/browse/KAFKA-6274
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Guozhang Wang
            Assignee: Guozhang Wang


When the source KTable is generated without the store name specified, the auto-generated store name use {{topic}} as the store name prefix. This would generate the store name as

{code}
Processor: KTABLE-SOURCE-0000000031 (stores: [windowed-node-countsSTATE-STORE-0000000029])
      --> none
      <-- KSTREAM-SOURCE-0000000030
{code}

We'd better improve the auto-generated store name as {[topic-name]-STATE-STORE-suffix}.
