Subject [jira] [Commented] (CASSANDRA-4295) move checkaccess into statement.prepare
Date Fri, 02 Nov 2012 18:25:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13489629#comment-13489629
] 

Aleksey Yeschenko commented on CASSANDRA-4295:
----------------------------------------------

bq. Could we add an invalidation hook to the API so that when permissions are changed, it
can notify us and we can go through the cache and throw out obsolete entries?

What if we enable caching for IAuthority2 only? And then invalidate the cache after calling
IAuthority2.grant() and revoke() in GrantStatement/RevokeStatement?
