-------------------------------------
Summary: Choose between sort merge and hash join based on size of
scanned data
Key: PHOENIX-4312
URL: https://issues.apache.org/jira/browse/PHOENIX-4312
Project: Phoenix
Issue Type: Test
Reporter: James Taylor

joined together. We should drive the determination of the join strategy based
on cost.
