Apurva Mehta commented on KAFKA-8558:
-------------------------------------
Bill, where are we with fixing this? Also, if I understand correctly, as trunk
stands today, if you upgrade from versions < 2.3 to trunk, and if you name your
join node, you will not reuse the join state store since the name will have
changed?
> KIP-479 - Add Materialized Overload to KStream#Join
> ----------------------------------------------------
>
> Key: KAFKA-8558
> URL: https://issues.apache.org/jira/browse/KAFKA-8558
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Bill Bejeck
> Assignee: Bill Bejeck
> Priority: Major
> Labels: needs-kip
> Fix For: 2.4.0
>
>
> To prevent a topology incompatibility with the release of 2.4 and the naming
> of Join operations we'll add an overloaded KStream#join method accepting a
> Materialized parameter. This will allow users to explicitly name state stores
> created by Kafka Streams in the join operation.
>
> The overloads will apply to all flavors of KStream#join (inner, left, and
> right).
