             Summary: Policy validation: resource uniqueness: store resource signature of a policy in database for faster check
                 Key: RANGER-359
                 URL: https://issues.apache.org/jira/browse/RANGER-359
             Project: Ranger
          Issue Type: Sub-task
            Reporter: Alok Lal


Currently we iterate over all policies for a service, a generate its resource signature and use that to enforce uniquness.  This can be computationally intensive and infeasible due to memory if there are several policies.  The resource signature of a policy could be kept in the database and kept up to date as resources change.  Then a database level search could allow for doing this check cheaply and robustly.
