> As far as I can tell, there is not way to use a UDT with {{CQLSSTableWriter}} since there
is no way to declare it and thus {{CQLSSTableWriter.Builder}} knows of no UDT when parsing
the {{CREATE TABLE}} statement passed.
> In terms of API, I think the simplest would be to allow to pass types to the builder
in the same way we pass the table definition. So something like:
> {noformat}
> String type = "CREATE TYPE myKs.vertex (x int, y int, z int)";
> String schema = "CREATE TABLE myKs.myTable ("
>               + "  k int PRIMARY KEY,"
>               + "  s set<vertex>"
>               + ")";
> String insert = ...;
> CQLSSTableWriter writer = CQLSSTableWriter.builder()
>                                           .inDirectory("path/to/directory")
>                                           .withType(type)
>                                           .forTable(schema)
>                                           .using(insert).build();
> {noformat}
> I'll note that implementation wise, this might be a bit simpler after the changes of
CASSANDRA-10365 (as it makes it easy to passe specific types during the preparation of the
create statement).
