David Hearnden commented on CASSANDRA-8108:
-------------------------------------------
Thanks Tyler, you helped me find an issue on my side - I had set the fetch size
to 1, which was too low for that query. I'm now setting the fetch size to the
expected number of results, and no longer see this issue.
