> Post CASSANDRA-1436, we'll be back to single Avro objects to describe schemas for client
and internal use: it would be a good opportunity to improve our handling of defaults and our
validation of config.*Metadata objects.
> Right now, we have multiple ways to convert a CfDef to a CFMetaData object (for example),
due to the differences between the defaults that should be chosen for a _new_ column family
(when we receive the CfDef from a client), versus an _existing_ column family after a new
setting has been added (deserializing a CfDef from disk). Finding a unified way to handle
these two (potentially different) default values would be excellent.
