compression is false; meanwhile a compressionBuffer is being allocated at every call - is that required?
if its needed - would it be possible to reuse the buffer later?

Since we are not trying to compress, I made the buffer null
Lets discuss on this, If compression can improve the performance, I can work on follow-up PR to do that work

Not very sure though, but I expected this was because we used to send empty to window operator query and that has been changed now. Let me check the actual difference and comment back.

… group by (apache#16658) Register a Ser-De for RowsAndColumns so that the window operator query running on leaf operators would be transferred properly on the wire. Would fix the empty response given by window queries without group by on the native engine.
