------------------------------------
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
