             Summary: Automatic co-partitioning of topics via automatic intermediate topic with matching partitions
                 Key: KAFKA-6182
                 URL: https://issues.apache.org/jira/browse/KAFKA-6182
             Project: Kafka
          Issue Type: New Feature
          Components: streams
            Reporter: Antony Stubbs


Currently it is up to the user to ensure that two input topics for a join have the same number of partitions. It would be great have Kafka streams detect this automatically, or at least give the user and easy way, and create an intermediate topic with the same number of partitions as the topic being joins with.

See https://docs.confluent.io/current/streams/developer-guide.html#joins-require-co-partitioning-of-the-input-data
