[GEODE-7666] Implementing the barebones code to clear a partitioned region

• Type: Sub-task
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Component/s: regions

Description

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.
