> 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.
