[jira] [Created] (RANGER-3519) Provide an option to optimize space needed by Trie objects

Abhay Kulkarni created RANGER-3519:
--------------------------------------

             Summary: Provide an option to optimize space needed by Trie objects
                 Key: RANGER-3519
                 URL: https://issues.apache.org/jira/browse/RANGER-3519
             Project: Ranger
          Issue Type: Bug
          Components: Ranger
            Reporter: Abhay Kulkarni
            Assignee: Abhay Kulkarni


When the number of policies (and/or tagged resources) is large, the data structures used by Ranger as indexes for policies (and/or tagged resources) may need a very large heap memory because they are optimized for fast lookup. It is desirable to be able to configure Ranger to have these structures optimized for space in order to keep the heap requirements within acceptable limit at the cost of somewhat slower lookup.
