             Summary: Tag lookup optimization: use prefix lookup to reduce number of evaluators attempted
                 Key: RANGER-1162
                 URL: https://issues.apache.org/jira/browse/RANGER-1162
             Project: Ranger
          Issue Type: Bug
          Components: plugins
    Affects Versions: 0.6.0
            Reporter: Madhan Neethiraj
            Assignee: Madhan Neethiraj


Based on the improvements seen in policy-evaluation response time, after changes in RANGER-1161, the logic to determine the tags for the accessed-resource can benefit with the same approach. Currently the policy engine attempts to match the resource with all service-resources. The number of evaluators attempted can be reduced by using a better arrangement/lookup of service-resources - like trie.
