[jira] [Created] (SENTRY-1896) Optimize retrieving roles for groups

Arjun Mishra created SENTRY-1896:
------------------------------------

             Summary: Optimize retrieving roles for groups
                 Key: SENTRY-1896
                 URL: https://issues.apache.org/jira/browse/SENTRY-1896
             Project: Sentry
          Issue Type: Improvement
          Components: Sentry
    Affects Versions: 2.0.0
            Reporter: Arjun Mishra
            Assignee: Arjun Mishra
             Fix For: 2.0.0


Right now when we get privileges from sentry, we pass in a provider like set of groups. Then we create a MSentryGroup object and then get roles using the .getRoles() method. However, DataNucleus takes too long and the fetch doesn't seem to be lazy. This is bad since we only need the "Role Names" for the group and not the entire Role object.  
Instead running a SQL like query and just getting roleNames will drastically improve performance
