AsyncEventScheduler (Imixs Workflow 6.0.3-SNAPSHOT API)

java.lang.Object
- org.imixs.workflow.engine.AsyncEventScheduler

```
@DeclareRoles("org.imixs.ACCESSLEVEL.MANAGERACCESS")
@RunAs("org.imixs.ACCESSLEVEL.MANAGERACCESS")
public class AsyncEventScheduler
extends Object
```
The AsyncEventScheduler starts a scheduler service to process async events in an asynchronous way by calling the AsyncEventService.
The AsyncEventScheduler runs on a non-persistent ejb timer with the interval 'ASYNCEVENT_PROCESSOR_INTERVAL' and an optional delay defined by 'ASYNCEVENT_PROCESSOR_INITIALDELAY'. To enable the processor 'ASYNCEVENT_PROCESSOR_ENABLED' must be set to true (default=false). 'ASYNCEVENT_PROCESSOR_DEADLOCK' deadlock timeout
In a clustered environment this timer runs in each cluster member that contains the EJB. So this means the non-persistent EJB Timer scales horizontal within a clustered environment – e.g. a Kubernetes cluster.

    The method delegates the event processing to the stateless ejb AsyncEventProcessor.
    Before processing the eventLog the method releases possible dead locks first. Both methods are running in separate transactions
