   @vvellanki, what I'm suggesting is to plan early and use the actual stats 
from the splits. You will need to do the planning at some point either way 
because you'll need to dispatch a task for each input split.
   
   As for the time taken to plan a scan with more columns, you should take a 
look at the table properties to control metrics that are kept in table 
metadata. The [metrics properties start with 
`write.metadata`](http://iceberg.apache.org/configuration/#write-properties).
