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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
