> 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).
