Use the data services view in Studio to discover databases or tables from a data service.
In order to use discovery, start a local cluster in the background during ESP perspective activation. When you start the local cluster, you may see projects that have run previously in other Studio sessions, because of the persistence feature.
If you have database definitions in a service.xml file from previous versions of ESP, migrate them to the data services format using the service.xml migration command of the streamingclusterutil command line utility.
