We noticed that in Q72 native WSCG is still slower than vanilla spark, some ideas below may improve performance.

  • postpone GetValue in WSCG when value is required.
  • BHJ build : we may decide hashmap initial size according to build table size
  • BHJ Get: optimize hashmap probe and add a fast cache
  • SMJ optimization: TBD
