angerszhu updated SPARK-47294:
------------------------------
Description:
Current OptimizeSkewInRebalanceRepartitions only support match
ShuffleQueryStageExec, this case only support SQL query, can't work when insert
since there have a project between ShuffleQueryStageExec and insert command
{code:java}
plan transformUp {
case p @ ProjectExec(_, stage: ShuffleQueryStageExec) if
isSupported(stage.shuffle) =>
p.copy(child = tryOptimizeSkewedPartitions(stage))
case stage: ShuffleQueryStageExec if isSupported(stage.shuffle) =>
tryOptimizeSkewedPartitions(stage)
} {code}
> OptimizeSkewInRebalanceRepartitions should support
> ProjectExec(_,ShuffleQueryStageExec)
