             Summary: Optimize tag-download to include only tags that have 
policies
                 Key: RANGER-1199
                 URL: https://issues.apache.org/jira/browse/RANGER-1199
             Project: Ranger
          Issue Type: Improvement
          Components: admin
    Affects Versions: 0.6.1, 0.6.0
            Reporter: Madhan Neethiraj


For the calls to download tags from plugins, Ranger Admin returns all the 
service-resources that have one or more tags associated. This can be optimized 
to include only service-resources that have tags for which policies exists.

For example, if tag-based policies exists for tags PII and PCI, Ranger Admin 
should return service-resources that are associated with PII or PCI tags only; 
any service-resource that is not associated with either of these tags should be 
excluded. In addition to reducing the size of the tag-download, this can 
improve policy-engine performance by not having to deal with tags that don't 
have policies.
