Persistence options
The Persistence Options tab specifies the correlator persistence settings Apama Studio will use when it runs this launch configuration.
*Enable correlator persistence — When set, this tells the correlator to start with the persistence option.
*Directory location — This specifies the location on disk of the persistent store used to preserve correlator state.
*Startup options — These options specify the startup behavior of the correlator with respect to how it handles its persistent store.
*Clear state and re-inject — Specifies that you want to clear the contents of the recovery datastore.
*Resume from persistent state — Specifies that the correlator will restart using the state from its persistent store as of the last committed snapshot.
*Prompt for startup options dialog during correlator launch — Specifies that Apama Studio will present a dialog when launching the application. The dialog asks whether to clear the correlator state information and re-inject the application code or to resume from the state information stored in the last committed snapshot.
