About KeyPartitioning: Spark does have something similar: [KeyGroupedPartitioning](https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/plans/physical/partitioning.scala#L378). It's pretty much like the current hash partitioning mechanism we have when leaf nodes are already partitioned, but with a different name. -- This is an automated message from the Apache Git Service.
