Darrel Schneider created GEODE-8386:
---------------------------------------

             Summary: SRANDMEMBER with negative count should return that many members
                 Key: GEODE-8386
                 URL: https://issues.apache.org/jira/browse/GEODE-8386
             Project: Geode
          Issue Type: Bug
          Components: redis
            Reporter: Darrel Schneider


When SRANDMEMBER is sent a negative count, it should return a number of items equal to the absolute value. uniqueness is not guaranteed.

 

{{SADD abc 123 456
SRANDMEMBER abc -1 -> 123
SRANDMEMBER abc -2 -> 123, 123 OR 123, 456, 456, 123 OR 456, 456
SRANDMEMBER abc -5 -> 123,123,456,123,456 OR any one of the 2^5 combinations...}}

see the redis unit tests and docs: unit/type/set -> SRANDMEMBER with <count> - hashtable
and documentation: [https://redis.io/commands/srandmember]

Currently, Geode Redis returns only up to as many members as there are in the set.
