      Description

      For easy debugging, the hash repartitioning have used CSV as the default intermediate data format. CSV file format may cause parsing overhead, and it may cause relatively large intermediate data to be transmitted via networks. We need to change it to RawFile or another efficient file format.

      Digging PartitionedStoredExec class is a good starting point for this issue.
