nabarun resolved GEODE-3148.
----------------------------
    Resolution: Won't Fix

> Replace ObjectOpenCustomHashSet with ConcurrentSkipListSet

>                 Key: GEODE-3148
>                 URL: https://issues.apache.org/jira/browse/GEODE-3148
>             Project: Geode
>          Issue Type: Bug
>          Components: querying
>            Reporter: nabarun

> After profiling the performance of queries such as SELECT DISTINCT e.id, e.value FROM
/region e, we could see that the bottleneck was caused by rehash / resizing operation of the
ObjectOpenCustomHashSet while adding new entries to the data structure.
> We experimented with ConcurrentSkipListSet and saw that performance was improved. ConcurrentSkipListSet
should be incorporated into Apache Geode if it passes all the testing.
