> 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.
