> Currently in derby, for an insert on a clob using setCharacterStream what
> will happen is , the entire stream will be materialized into a char array and
> sent to store for the insert.
> see - SQLVarChar.normalize, where getString() is called and
> SQLChar.getString() will materiliaze the entire stream into a char array (
> SQLChar.readExternal).
> The store layer must actually drive the streaming.
