Hello all, While writing some new test cases for foreign key joins (as accepted in KIP-213), I realized that there was an oversight in the review process: we only proposed to add join methods that take a Materialized parameter.
This poses an unnecessary burden on users who don't _need_ to materialize the join result, which could be quite a lot of state and changelog topic data. I filed https://issues.apache.org/jira/browse/KAFKA-9058 and then https://github.com/apache/kafka/pull/7541 to fix it. I've updated the KIP page accordingly as well. This change consists solely of adding the missing method overloads, and doesn't change the behavior or semantics of the operation at all. Thanks, -John
