             Summary: Implementing the barebones code to clear a partitioned region
                 Key: GEODE-7666
                 URL: https://issues.apache.org/jira/browse/GEODE-7666
             Project: Geode
          Issue Type: New Feature
          Components: regions
            Reporter: Nabarun Nag


A clear() Java API on Partitioned Region
 * Acquires a distributed lock
 * Declares itself the co-ordinator
 * Gets the primary list of buckets and sends clear messages
 * After primaries are cleared and then clear messages are sent to the secondaries

If all the steps are successful then API return success

 

Acceptance :
 * Unit tests to have complete code coverage
 * DUnit tests where clear op on Partitioned Region is successful (Region size = 0)
 * DUnit test where all concurrent clear() calls are made. One operation should succeed while sending appropriate messages to the failing API calls
 * Test coverage for PartitionedRegion with redundancy levels of 0 and more.
 * Test coverage to when a member departs in this scenario
 * Test coverage to when a member restarts in this scenario


NOTE: 

Analyze if there needs to be tests for offheap regions. If it is needed then write the tests and make the appropriate code changes to make the offheap tests pass.
