> Project: Ranger
> Issue Type: Improvement
> Components: Ranger
> Reporter: Abhay Kulkarni
> Assignee: Abhay Kulkarni
> Priority: Major
> Fix For: 2.1.0
>
>
> Currently, every change to any tag/service-resource/service-resource->tag
> mapping causes complete rebuilding of portions of policy-engine that map
> accessed resource to their tags. There are several disadvantages:
> 1. Compute time for rebuilding
> 2. Large traffic from ranger-admin to each of the plugins
> 3. Large load on JVM memory system because of frequent complete rebuilding of
> portions of policy-engine.
> It will be more optimal to communicate only the changes to tags and apply
> them to existing policy-engine.
