----------------------------
Summary: Support million policies in ranger.
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
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.
