Arjun Mishra updated SENTRY-1896:
---------------------------------
Description:
Right now when we get privileges from sentry, we pass in a provider like set of
groups. Then we create a MSentryGroup object for each group and then get roles
using the .getRoles() method. This is bad since we only need the roleNames for
the group and not the entire Role object.
Instead running a SQL like query and just getting roleNames will drastically
improve performance

Right now when we get privileges from sentry, we pass in a provider like set of
groups. Then we create a MSentryGroup object for each group 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 roleNames for the
group and not the entire Role object.
