Class SyncService

java.lang.Object

org.imixs.archive.service.resync.SyncService

public class SyncService
extends Object

The SyncService synchronizes the data of a Imixs-Worklfow instance with the cassandra cluster. The synchonrization can be started by the method sync(). The SyncService is implemented as a SingleActionTimer so the sync can run in backgroud.

The service automatially starts during deployment. When all the data is synchronized (syncpoint == last snapshot), the service terminates.

To access the data form the Imixs-Workflow instance uses RemoteAPIService.
