raminqaf opened a new pull request, #15601: URL: https://github.com/apache/kafka/pull/15601
#### Description The introduced changes provide a cleaner definition of the join side in KStreamKStreamJoin. Before, this was done by using a Boolean flag, which led to returning a raw LeftOrRightValue without generic arguments because the generic type arguments depended on the boolean input. Tests of @gharris1727 from his [PR](https://github.com/apache/kafka/pull/15513) have been adopted to check the type-sefty of the joins. #### Summary of testing strategy Unit tests have been added for the new _JoinSide_ enum. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
