---------------------------------------
Summary: SUNIONSTORE, SINTERSTORE, and SDIFFSTORE should delete
the target key if the computed set is empty
Key: GEODE-8387
URL: https://issues.apache.org/jira/browse/GEODE-8387
Project: Geode
Issue Type: Bug
Components: redis
Reporter: Darrel Schneider
The current impl of SUNIONSTORE, SINTERSTORE, and SDIFFSTORE set the
destination to an empty set if the computed set is empty. But they should
instead in that case delete the destination. This is true if the read keys do
not exist.
If the read keys exist but are not sets then the commands should fail with a
WRONGTYPE error.
