Jacek Lewandowski commented on CASSANDRA-15962:
-----------------------------------------------
It looks like in {{BTreeRow}} where have a missing piece in a method:
{code}
public Row filter(ColumnFilter filter, DeletionTime activeDeletion, boolean
setActiveDeletionToRow, CFMetaData metadata)
{code}
when the column is not queried, but it is required (cell timestamp. >= row
timestamp), we should actually return empty cell rather than a cell with data
or no cell at all
> Digest for some queries is different depending whether the data are retrieved
> from sstable or memtable

>
> 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
