[jira] [Created] (KAFKA-5680) Don't materliaze physical state stores in KTable filter/map etc operations

Damian Guy created KAFKA-5680:
---------------------------------

             Summary: Don't materliaze physical state stores in KTable filter/map etc operations
                 Key: KAFKA-5680
                 URL: https://issues.apache.org/jira/browse/KAFKA-5680
             Project: Kafka
          Issue Type: Bug
            Reporter: Damian Guy


Presently, for IQ, we will materialize physical state stores for {{KTable#filter}} {{KTable#mapValues}} etc operations if the user provides a {{queryableStoreName}}. This results in changelog topics, memory, disk space that we can avoid by providing a view on the original state store.
