      Description

      Not sure into which category should I assign this ticket.

       

      Basically when reading using certain column filters, the digest is different depending whether we read from sstable and memtable. This happens on trunk and cassandra-3.11 branches. However it works properly on cassandra-3.0 branch.

       

      I'm attaching a simple test for trunk to demonstrate what I mean. 

       

      Please verify my test and my conclusions
