[GitHub] [arrow-datafusion] Dandandan opened a new issue #461: Add support for semi (hash) join
Dandandan opened a new issue #461:
URL: https://github.com/apache/arrow-datafusion/issues/461
*Is your feature request related to a problem or challenge? Please describe what you are trying to do.*
We should support semi join. This can also be used to execute IN and EXISTS.
Explicit syntax for this join could be supported too.
*Describe the solution you'd like*
Implement semi join in DataFusion. This can probably utilize most of the existing code in HashJoinExec
*Describe alternatives you've considered*
