Jorge created ARROW-9420:
----------------------------
Summary: Add repartition/shuffle plan
Key: ARROW-9420
URL: https://issues.apache.org/jira/browse/ARROW-9420
Project: Apache Arrow
Issue Type: Improvement
Components: Rust - DataFusion
Reporter: Jorge
Some operations (group by, join, over(window.partition_by)) greatly benefit
from hash partitioning.
This is a proposal to add hash partitioning (based on a expression) to this
library, so that optimizers can be written to optimize the plan based on the
required hashing.
