alamb opened a new pull request #807:
URL: https://github.com/apache/arrow-datafusion/pull/807


   # Which issue does this PR close?
   
   Re https://github.com/apache/arrow-datafusion/issues/790 by implementing a new design for group by hash
   
    # Rationale for this change
   1. The design in https://github.com/apache/arrow-datafusion/issues/790 calls for hashing the input to group by hash in a manner almost-identical with `create_hashes` in hash_join, which I hope to reuse
   2. It turns out the hashing algorithm is also used by repartition exec as well
   
   # What changes are included in this PR?
   Move `create_hashes` into hash_utils so it can be shared with hash_join and hash_aggregate.
   
   # Are there any user-facing changes?
   No. This PR just moves code, No functional changes intended.
