Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Currently FilterExec filters/outputs all columns present in the filter expression. This does unnecessary work, as we might not need certain columns later.
Describe the solution you'd like
Add projection to Filter/FilterExec and use it before passing the RecordBatch to the arrow kernel.
This saves a bit of computation, especially when there is only one column in the projection (fast case).
Also update the schema based on the projection.
