Review comment:
yes, it will keep on executing the query until it's returning 0 results.
There is a slight chance that this could get executed even before the region
is populated, that's why I put a pollDelay there to reduce this chance.

> Key: GEODE-7672
> URL: https://issues.apache.org/jira/browse/GEODE-7672
> Project: Geode
> Issue Type: Sub-task
> Components: regions
> Reporter: Nabarun Nag
> Assignee: Jianxia Chen
> Priority: Major
> Labels: GeodeCommons, pull-request-available
>
> Clear operations are successfully updates the OQL indexes
>
> Acceptance :
> * Passing Dunit tests where OQL queries using indexes return correct results
> after the region is cleared
> * clear operation and index updates are successful when clear operation is
> executed when the puts are occurring which are trying to update the OQL index.
> * Unit tests to ensure that index sizes are zero after the region is cleaned
> * Test coverage to when a member departs in this scenario
> * Test coverage to when a member restarts in this scenario
> * Unit tests with complete code coverage for the newly written code.
>
> analyze if these tests are needed for offheap?
