[GitHub] [arrow-datafusion] Dandandan opened a new issue #460: Add support for anti (hash) join

Dandandan opened a new issue #460:
URL: https://github.com/apache/arrow-datafusion/issues/460


   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   We should support anti join. This can also be used to execute `NOT IN` and `NOT EXISTS`.
   Eplicit syntax for this join could be supported too.
   
   **Describe the solution you'd like**
   Implement anti join in DataFusion. This can probably utilize most of the existing code in `HashJoinExec`
   
   **Describe alternatives you've considered**
   
   
   **Additional context**
