Russ Hatch commented on CASSANDRA-6643:
---------------------------------------
bq. can never be fully qualified and always implicitly refer to the keyspace of
whatever query the name is part of
Does that mean user types couldn't be created or added like so? (from the
global keyspace):
{noformat}
cqlsh> CREATE TYPE user_types.simple_type (user_number int);
cqlsh> CREATE TABLE user_types.simple_table (
... id uuid PRIMARY KEY,
... number simple_type
... );
{noformat}
> Limit user types to the keyspace they are defined in

> Key: CASSANDRA-6643
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6643
> Project: Cassandra
> Issue Type: Bug
> Environment: java version "1.7.0_51"
> cassandra from trunk, 4b54b8...
> Reporter: Russ Hatch
> Assignee: Sylvain Lebresne
> Priority: Minor
> Fix For: 2.1 beta2

> I'm not 100% certain this is a bug.
> The current syntax for "alter type rename" requires the keyspace on the old
> and new table name (if a keyspace is not active). So, to rename the type
> 'foo' to 'bar', you have to issue this statement:
> ALTER TYPE ks.foo rename to ks.bar .
> As a result, this syntax will also allow renaming the type into another
> existing keyspace, which updates the metadata in system.schema_usertypes.
> I'm wondering if perhaps we can omit the second keyspace prefix and
> implicitly rename into the same keyspace.
> To reproduce:
> {noformat}
> cqlsh> create keyspace user_types with replication =
> {'class':'SimpleStrategy', 'replication_factor':3} ;
> cqlsh> create keyspace user_types2 with replication =
> {'class':'SimpleStrategy', 'replication_factor':3} ;
> cqlsh> CREATE TYPE user_types.simple_type (user_number int);
> cqlsh> alter type user_types.simple_type rename to user_types2.simple_type;
> {noformat}
> Renaming to another keyspace is also possible when a keyspace is active, like
> so:
> {noformat}
> cqlsh:user_types> alter type simple_type rename to user_types2.simple_type;
> {noformat}
