   I am currently working on [gluten](https://github.com/oap-project/gluten) and clickhouse backend. Our team try to implement a filter push down like velox but using clickhouse expression evaluate framework which is not good since we have to build full `Column` before filter operation.
   
   The paper gives right direction, and I think we should implement filter push donw like this in  apache arrow.
   
   Would we have a meeting on this?
