[GitHub] [arrow-datafusion] Dandandan commented on issue #2165: Optimize InList implementation with native types rather than ScalarValue

Dandandan commented on issue #2165:
URL: https://github.com/apache/arrow-datafusion/issues/2165#issuecomment-1089292408

   In addition to higher memory usage and dispatching overhead there are two extra sources of overhead:
   
   * Having to convert all values from array items to `ScalarValue`
   * Hashing a `Scalarvalue` is slower than hashing a native type.
