------------------------------------
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.
