> 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.
