[GitHub] [arrow-datafusion] metesynnada opened a new pull request, #5864: Enhance Asynchronous Performance of SHJ Implementation

metesynnada opened a new pull request, #5864:
URL: https://github.com/apache/arrow-datafusion/pull/5864

   # Which issue does this PR close?
   
   Closes https://github.com/apache/arrow-datafusion/issues/5714.
   
   # Rationale for this change
   
   To optimize the asynchronous performance of the `SymmetricHashJoin` operator, we propose merging the two child streams using `futures::select`. This will enable simultaneous polling of both streams and execute the branch corresponding to the future that completes first.
   
   # What changes are included in this PR?
   
   - Single stream SHJ implementation on `poll_next()`
   - Refactor on fifo tests and reduce code duplication.
   
   # Are these changes tested?
   
   Yes
   
   # Are there any user-facing changes?
   
   No
