> Project: Cassandra
> Issue Type: Improvement

> Fix For: 4.1

>
> With our current auth querying setup, you can end up with a thundering herd
> on reconnect due to delays on auth resolution.
> We should instead allow the ability to do a 'select' on all roles and
> pre-load the cache before turning on native transport. Notably, this could
> present some unacceptable delays on start with a very large count of users
> (thousands), or someone who uses a third party auth system rather than the
> built-in authorizer so this should be configurable and opt-in.
