Summary: Allow custom partitioning in foreign-key joins
Key: KAFKA-9302
URL: https://issues.apache.org/jira/browse/KAFKA-9302
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: Matthias J. Sax
In the 2.4 release, we introduces foreign-key joins via KIP-213 (KAFKA-3705).
However, the API does not allow to work with a custom partitioning strategy,
ie, it always assumes that the both input tables use the default partitioner.
We should allow to pass in a custom partitioner for each side that can be used
when writing in the repartitions topics.
