---------------------------------------
Summary: RedisSet spop and srandmember should not copy entire
MemberSet
Key: GEODE-9904
URL: https://issues.apache.org/jira/browse/GEODE-9904
Project: Geode
Issue Type: Improvement
Components: redis
Reporter: Darrel Schneider
The current implementation of RedisSet spop and srandmember always copy the
entire MemberSet. So if you have a redis set with a million items, and than ask
for one random one, instead of it reading just one of the items out of the set
it first copies the entire set.
The call that makes the copy is "members.toArray". It should be pretty easy to
add spop and srandmember support to the MemberSet super class. Since MemberSet
uses a flat array to store its items it should work well with supporting
indexing of its array to get a random element.
