[jira] [Created] (KAFKA-7502) Cleanup KTable materialization logic in a single place

Guozhang Wang created KAFKA-7502:
------------------------------------

             Summary: Cleanup KTable materialization logic in a single place
                 Key: KAFKA-7502
                 URL: https://issues.apache.org/jira/browse/KAFKA-7502
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Guozhang Wang


Today since we pre-create all the `KTableXXX` operator along with the logical node, we are effectively duplicating the logic to determine whether the resulted KTable should be materialized. For example, in `KTableKTableJoinNode` and in `KTableImpl#doJoin`. This is bug-vulnerable since we may update the logic in one class but forgot to update the other class.
