On top of #19588 , when delta.checkpoint-filtering.enabled setting is set to true , read only the statistics which are relevant for the query and not all the statistics available.

If a query makes use of 5 fields out of 90 fields of a table, we should read only the statistics corresponding to the 5 fields requested.
