Sam Tunnicliffe commented on CASSANDRA-14956:
---------------------------------------------
Pushed a 2.1 branch after discussion on dev@ about one last 2.1 release before
EOL. Unfortunately, CircleCI no longer supports v1.0 job configuration so a CI
run is going to need the v2.0 config backporting (which we may want to do
before a release anyway).

> Paged Range Slice queries with DISTINCT can drop rows from results

> Key: CASSANDRA-14956
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14956
> Project: Cassandra
> Issue Type: Bug
> Components: CQL/Interpreter
> Reporter: Sam Tunnicliffe
> Assignee: Sam Tunnicliffe
> Priority: Major
> Fix For: 2.2.14
>
>
> If we have a partition where the first CQL row is fully deleted (possibly via
> TTLs), and that partition happens to fall on the page boundary of a paged
> range query which is using SELECT DISTINCT, the next live partition *after*
> it is omitted from the result set. This is due to over fetching of the pages
> and a bug in trimming those pages where overlap occurs.
> This does not affect 3.0+.
