> virtual  column   “INPUT__FILE__NAME” does not exclude files before map .
> If I have three files I only want it to deal one file of three files, Then 
> the map count will be 3 and will read all three files , so It's only tell 
> what's file the line in and then filter it but not filter before map input 
> path.
