The name of the keyspace being part of the partition key is not useful, the table_id already uniquely identifies the table. The keyspace name being part of the key, means that code wanting to interact with this table, often has to resolve the table id, just to be able to provide the keyspace name. This is counter productive, so make the keyspace_name just a static column instead, just like table_name already is. Fixes: #16377 Closes scylladb/scylladb#16881
