Arjun Mishra commented on SENTRY-1937:
--------------------------------------
I agree we should optimize this further. But I don't think listing roles by
group name is a hot path. Listing privileges for provider (groups/users) is
used with more frequently. Listing roles is probably only used with query like
_SHOW ROLES_ or _SHOW CURRENT ROLES_
> Optimize performance for listing sentry roles by group name

> It seems that the most common request is listing sentry roles by group name,
