This is a work in progress PR to replace
KeyGroupedPartitioningwithKeyedPartitioningand separate partitiong grouping logic fromBatchScanExecto a newGroupPartitionsExecoperator.KeyedPartitioningrepresents a partitioning where partition keys are known. It can be grouped (clustered) or not by partition keys. When grouping is required the new operator can be inserted into a plan at any place (similary to how exchanges are inserted) and so creating the necessary grouped/replicated partitions by keys.Why are the changes needed?
To solve the issue of unecessary partition grouping (#53859) and restore
BatchScanExeccleanness and simplicity.Does this PR introduce any user-facing change?
No.
