--------------------------------------
Summary: Support for Incremental tag updates to improve performance
Key: RANGER-2510
URL: https://issues.apache.org/jira/browse/RANGER-2510
Project: Ranger
Issue Type: Improvement
Components: Ranger
Reporter: Abhay Kulkarni
Assignee: Abhay Kulkarni
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.
