Since skewed partitions and coalesced partitions can appear together in one custom shuffle reader, I think it's reasonable to add the `numCoalescedPartitions` metric. `numPartitionsToCoalesce` is a bit overkill to me. If we can know the original number of partitions of the shuffle (ShuffleExchangeExec can report it), we can get a sense of the custom shuffle reader by looking at num skewed partitions/splits and num coalesced partitions. -- This is an automated message from the Apache Git Service.
