# 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. -- This is an automated message from the Apache Git Service.
