   > what about this case: day(ts)=1 versus col1 > 13. where ts is a partition 
column while col1 is not. and some v2 data source implementation is capable of 
pushing that day function down. ? what will happen?
   
   Seems to me the current implementation can only push down filters which are 
in the format of attribute cmp lit. Could you copy and paste the plan that 
pushes down `day(ts)=1`?
