   > Uh, I just want to know why we not refactor FileScanBuilder by replaces 
SupportsPushDownCatalystFilters to SupportsPushDownV2Filters ?
   
   We actually intentionally want to push down catalyst Expression instead of 
filter in file source, because in file source we need to do partition pruning, 
which uses catalyst Expression.
