[jira] [Commented] (CASSANDRA-16404) Provide a nodetool way of
invalidating auth caches
[ https://issues.apache.org/jira/browse/CASSANDRA-16404?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17375375#comment-17375375 ]
Benjamin Lerer commented on CASSANDRA-16404:
--------------------------------------------
[~azotcsit] Once again sorry for the delay.
I did not realized that the JMX interface for that part of the code tend to be nested within the implementation classes. So I would do the same despite what I said earlier. Otherwise the patch look good to me but we would need another +1 from a committer.
[~samt] Your are familiar with that part of the code. Would you have some time for a review?

> We currently have nodetool commands to invalidate certain caches like KeyCache, RowCache and CounterCache.
> Being able to invalidate auth caches as well can come in handy in situations where, critical backend auth changes may need to be in effect right away for all the connections, especially in configurations where cache validity is chosen to be for a longer duration. An example can be that an authenticated user "User1" is no longer authorized to access a table resource "table1" and it is vital that this change is reflected right away, without having to wait for cache expiry/refresh to trigger.
