-----------------------------------------
Summary: Prewarm role and credentials caches to avoid timeouts at
startup
Key: CASSANDRA-16958
URL: https://issues.apache.org/jira/browse/CASSANDRA-16958
Project: Cassandra
Issue Type: Improvement
Components: Feature/Authorization
Reporter: Josh McKenzie
Assignee: Josh McKenzie
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.
