Aleksey Yeschenko commented on CASSANDRA-4295:
----------------------------------------------
So the proposed solution is to use Guava's
CacheBuilder<IResource,Set<Permission>> for a map in ClientState. TTL will be
configurable through cassandra.yaml and will be set to 1 second by default.
> Implement caching of authorization results

> 1.2 will come with default IAuthority implementation that stores permissions
> in Cassandra, and each permission check will involve at least 1 Cassandra
> read. Some form of authorization result caching is very important for this
> scenario.
