Stu Hood updated CASSANDRA-1554:
--------------------------------

    Attachment: v1-0004-minimize-object-creation.txt

* I think we need to minimize object creation in 
ClientState.hasColumnFamilyAccess: this was the intention of the member 
ArrayList<Object> in ClientState before, but I think it's more important now 
that it's called for every CF touch. Attaching an 0004 which we can consider in 
a different issue if you want.

Thanks for working on this Eric... much appreciated.

> extend authorization to column families

> Authorization is now based on a hierarchy of resources, but the hierarchy 
> only extends as far as keyspaces.  At the very least, it should be possible 
> to implement an authority that can distinguish between the creation, 
> modification and deletion of column families, and reading and writing the 
> data contained in them.
