Arjun Mishra commented on SENTRY-1937:
--------------------------------------
[~akolb] What was the query you ran? Based on my code review, I saw that the
getTSentryRolesByGroup method is not used to get privileges but just list
roles. Was your query simply show roles? To get privileges we use
getRoleNamesForGroups() method which is similar to the code you have above.
> Optimize performance for listing sentry roles by group name

> It seems that the most common request is listing sentry roles by group name,
> so this is a very hot path. It is important to optimize its performance,
> especially in the presence of many roles.
