> Classpath contexts are assigned to a table via the table configuration. You
> can test at scale by cloning your table and assigning a new classpath context
> to the cloned table. However, you would also need to change your application
> to use the new table names and since we cannot disable compactions you would
> start to consume more space in the filesystem for that table. We can support
> users passing in a context name to use for the scan on existing tables.
