--------------------------------------------
I'll check if it is a mysql 5.1 issue. Let me try the same with mysql 5.6, I'll
get back with the results during the next week.
> REST search queries make Ranger incredibly slow

> Key: RANGER-2149
> URL: https://issues.apache.org/jira/browse/RANGER-2149
> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Affects Versions: 0.7.0
> Reporter: Alexander Posledov
> Assignee: Pradeep Agrawal
> Priority: Major
> Attachments: bulkpolicytest.png, totalPolicy.png
>
>
> If amount of Ranger policies is relatively big (3000-4000), then REST search
> queries (e.g. search policy by name) make Ranger very slow. Example:
> curl -u admin:admin -X GET
> http://host:6080/service/plugins/policies?policyName=somePolicyName
> 2-3 such queries (if we have ~3k policies) can cause too long delays even for
> simple requests, while these searches aren't completed. In some cases, when
> we ran several search queries simultaneously, this Ranger behavior caused 9
> min delay for simple adding a new policy.
