Tyler Hobbs commented on CASSANDRA-6857:
----------------------------------------
Thanks. I thought something might be missing; that makes sense.
It looks like some a ColumnFamilyStoreTest method needs to be updated for the
2.0 patch to compile (you just need to add the countCQL3Rows argument to two
makeExtendedFilter() calls). Other than that, +1.
> SELECT DISTINCT with a LIMIT is broken by paging

> The paging for RangeSliceCommand only support the case where we count CQL3
> rows . However, in the case of SELECT DISTINCT, we do actually want to use
> the "count partitions, not CQL3 row" path and that's currently broken when
> the paging commands are used (this was first reported on the [Java driver
> JIRA|https://datastax-oss.atlassian.net/browse/JAVA-288] and there is a
> reproduction script there).
