Bugs: RANGER-2499
https://issues.apache.org/jira/browse/RANGER-2499
Repository: ranger
Description
-------
**Problem Statement:** Ranger takes an extremely long time to import bulk
policies.
**Current performance(Without patch):**
Time taken to import 500 policies : 27+ Minutes
Time taken to import 1000 policies : 81+ Minutes
**Proposed Solution:**
in the bulk policy creation/deletion operation proposed patch shall call
EntityManager.flush() and EntityManager.clear() after processing a batch of 10
records.
** Note: **
Most of the changes in this patch comes from revert work of RANGER-2493 as I am
trying to generalize the solution for bulk create and update policies also.
Important changes are:
1) bulkModeOnlyFlushAndClear() method in the RangerBizUtil.java class.
2) call to bulkModeOnlyFlushAndClear() from ServiceREST and ServiceDBStore
wherever bulk create or update is made.
3) batch create/delete optimization and batch is configurable through
ranger-admin-default-site.xml file
4) few null checks in the existing code.
