Bugs: SENTRY-1944
    https://issues.apache.org/jira/browse/SENTRY-1944


Repository: sentry


Description
-------

When Solr is using Sentry server for authorization, it issues a lot of calls to 
getGroupsByRoles() function in DelegateSentryStore.

This function isn't very efficient - it walks over each role in the set, 
obtains role by name, get groups for each role, and collects all group names 
into a set.

It may be possible to optimize it.

Also, in SentryGenericPolicyProcessor class method list_sentry_roles_by_group() 
would make N transactions to build the roles to set of groups map. Instead, 
make it to a single transaction. This will significantly speed up operation

Attach one or more files to this issue
