Madhan Neethiraj commented on RANGER-2883:
------------------------------------------
[~ramackri] - updating of policy cache incrementally has been in place since
Ranger 2.0, via RANGER-2341.
> Update RangerServicePoliciesCache incrementally when delete/update/add
> instead of reloading all policies from the db store

> Key: RANGER-2883
> URL: https://issues.apache.org/jira/browse/RANGER-2883
> Project: Ranger
> Issue Type: Improvement
> Components: Ranger
> Affects Versions: 2.0.0, 1.2.0
> Reporter: star
> Assignee: star
> Priority: Major
>
> To ensure strong consistency of RangerServicePoliciesCache with db store, all
> policies will be reload after even a single delete/update/add operation.
> While reloading all policies from db store is very time consuming. So it's
> impossible to add a million policies through http interface.
