             Summary: Review and update database schema for ranger policies to minimize database queries/updates
                 Key: RANGER-2203
                 URL: https://issues.apache.org/jira/browse/RANGER-2203
             Project: Ranger
          Issue Type: Improvement
          Components: Ranger
    Affects Versions: master
            Reporter: Abhay Kulkarni
             Fix For: master


Currently, ranger policies are fully normalized and stored in a multiple Relational database tables. There is a performance overhead incurred when retrieving a ranger policy, as multiple database accesses are required to fully reconstruct it. This is significant when there are large ranger policies (that is, the number of resources addressed by the policy is large), and/or when there is a large number of ranger policies in an installation.

This Jira tracks alternate design of database schema, where a policy is stored in a de-normalized way, in its entirely, in one database table (preferably as a JSON string).
