Daniël Heres created ARROW-12439: ------------------------------------ Summary: [Rust] [DataFusion] Add support for eliminating hash repartition Key: ARROW-12439 URL: https://issues.apache.org/jira/browse/ARROW-12439 Project: Apache Arrow Issue Type: Bug Reporter: Daniël Heres
If the intermediate data is already partitioned on a certain expression (key), the repartition doesn't have to be added (in a join), or should be removed in an optimization rule. This will avoid having to repartition (and maybe shuffle in Ballista). -- This message was sent by Atlassian Jira (v8.3.4#803005)
