    Description

      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.
