Jacek Laskowski created KAFKA-8787: -------------------------------------- Summary: Report ValidationException when topology has state stores with no processors associated Key: KAFKA-8787 URL: https://issues.apache.org/jira/browse/KAFKA-8787 Project: Kafka Issue Type: Improvement Components: streams Affects Versions: 2.3.0 Reporter: Jacek Laskowski
It is possible to build and run a topology with a single state store only (and no processors). It should not actually be possible as it does make no sense (and could be confusing). It is similar to registering a state store no processor uses. It'd be nice to it have an "analysis/validation error" if a topology has a state store with no processor attached.
