             Summary: Support Columnar Shuffle
                 Key: HIVE-29410
                 URL: https://issues.apache.org/jira/browse/HIVE-29410
             Project: Hive
          Issue Type: Wish
            Reporter: yongzhi.shao


anyone thought about plugging Celeborn’s *columnar shuffle* (compressed column 
batches) into Hive/Tez?
Smaller traffic, less CPU, zero row objects—seems like free perf for wide 
tables.
