Sylvain Lebresne commented on CASSANDRA-9186:
---------------------------------------------
Honestly, I'm hoping we'll get rid of AbstractType in schema tables sooner than
later with CASSANDRA-6717, and that's more than likely to happen before we
support non-frozen UDT, so I'm not convinced it's worth getting too fancy here
(if we were to introduce a {{FrozenType}}, not only the drivers will have to
handle them but upgrades too. And then we'll still have to deal with
CASSANDRA-6717 later anyway. So better having to deal with this only once with
CASSANDRA-6717). Typically, just making it an assumption than {{UserType}} and
{{TupleType}} are frozen would be imo good enough for now (so option 3 really).
And as Robert said, if it does happen that we support non-frozen UDT before
CASANDRA-6717, we can easily use a separate class name for them.

> {code}

> use functionmetadatatest ;
> CREATE TYPE udtx (x int);
> CREATE FUNCTION u_frozen(u frozen<udtx>)RETURNS int LANGUAGE java AS 'return

> u_frozen | ['udtx'] |
> ['org.apache.cassandra.db.marshal.UserType(functionmetadatatest,75647478,78:org.apache.cassandra.db.marshal.Int32Type)']
> {code}
> Problem is that {{UserType}} and {{TupleType}} do not have a _frozen_ (or
> _isMultiCell_) attribute. A conversion from type to cql3type therefore loses
> the _frozen_ status.
