Gary Dusbabek commented on CASSANDRA-932:
-----------------------------------------

I'd prefer for this ticket to actually use Table.getColumnFamilyStore(int cfId) instead of merely deprecating Table.getColumnFamilyStore(String cfName).

This probably means pushing cfid into a few places where it currently isn't (QueryPath is the big one).

Is that too much work to chew off?

> CF.id() should be used in place of CF.name() for looking up column families.  
> In pragmatic terms this means that:
> * maps that store CF or CFS should use id as the key.
> * CF.name() should be eliminated and replaced by a toString() that includes the cfid and name.
> * other things I can't immediately think of.
> We might even go so far as to change the way we name the sstable files to use cfid instead of name.  This would make renaming CFs a simpler (and quicker) operation.
