>
> 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.
