14 - sandbox_subcluster

Sandboxes a subcluster in an Eon Mode database.

Sandboxes a subcluster in an Eon Mode database. All hosts in the subcluster must be up. When you sandbox a subcluster, its hosts immediately shut down and restart; the subcluster becomes sandboxed after the hosts start back up.

A sandbox can contain multiple subclusters, and subclusters in the sandbox can interact with each other. If you want to isolate subclusters, they must be in separate sandboxes.

Note

Subcluster sandboxing should be used for testing database changes or upgrades in a safe, isolated environment and should not be used for production subclusters. For example, you can create sandboxes and then upgrade Vertica in those sandboxes.
