> Rewrite topology to allow for overlapping unequal topic subscriptions

> Key: KAFKA-10721
> URL: https://issues.apache.org/jira/browse/KAFKA-10721
> Project: Kafka
> Issue Type: Improvement
> Components: streams

> Priority: Minor
> Labels: newbie++

> Minor followup improvement to KAFKA-6687 in which we rewrite the topology to
> make it possible for a user to subscribe multiple KStream/KTables to the same
> topic or identical set of topics. We could further extend this to make it
> possible for multiple KStream/KTables to be subscribed to overlapping but not
> identical sets of topics, ie
> {code:java}
> KStream streamA = builder.stream("topic");
> KStream streamB = builder.stream("topic", "other-topic"); {code}
> One way to do this would be to break up multiple-topic source nodes into
> multiple single-topic sources that get merged together in the child node.
