Oracle Endeca Workbench deployed with a preview Dgraph

This deployment approach calls for a new Dgraph to be configured in the production environment to serve as the Workbench preview Dgraph.

This Dgraph is updated along with others in the production environment each time an update is processed, but it does not serve traffic for the production application. Instead, this Dgraph is used for preview by Oracle Endeca Workbench.

By default, Oracle Endeca Workbench uses an EAC script to update MDEX Engines with new configuration each time the Save Changes button is pressed. With this deployment approach, the default functionality would update each production Dgraph in addition to the preview Dgraph. There are two ways to override this default behavior.
