>
> When dropping a ColumnFamily with row cache enabled, then row cache is not 
> invalidated for this CF.
> This can be a bit annoying if the ColumnFamily is recreated because it will 
> be empty, but row cache won't.
> Note : this is similar to a "TRUNCATE" command (and TRUNCATE does invalidate 
> the cache...)
> Attached is patch which removes the rows of the currently dropped CF from row 
> cache.
