> Key: RANGER-2658
> URL: https://issues.apache.org/jira/browse/RANGER-2658
> Project: Ranger
> Issue Type: Improvement
> Components: Ranger
> Affects Versions: 1.2.0
> Reporter: star
> Assignee: star
> Priority: Major
>
> We have nearly a million policies in Tencent. We found many problems by
> deploying ranger(1.2.0) in such a large scale. It seems that ranger is
> originally not designed to support large scale policies.
> If we would like to support a million policies, the following issues should
> be emphasized.
> 1. Policy import is very slow. It takes us a couple of days to import
> those policies .
> 2. It takes a long time (more than 10s) to search policies by name or
> user/group in ranger admin. Because it directly go through all policies in
> cache instead of search from index of database.
> 3. It will consume 8GB memory in user process.
> Above problems are relieved in 2.x, but it is not enough.
