> As part of the auto-parallelism feature, ordered partitioned KV output's partition stats are sent to ShuffleVertexManager via VertexManagerEvent. But this isn't available for unordered partitioned output. Having {{UnorderedPartitionedKVWriter}} send partition stats will enable the auto-parallelism support for unordered KV or other custom data routing mechanisms that depend on partition size.
