Create non-blocking process instances
Prerequisites​
- Run the Zeebe broker with endpoint 
localhost:26500(default). - Run the deploy a process example.
 
NonBlockingProcessInstanceCreator.java​
long instancesCreating = 0;
while (instancesCreating < numberOfInstances) {
    // this is non-blocking/async => returns a future
    final ZeebeFuture<ProcessInstanceEvent> future =
        client.newCreateInstanceCommand().bpmnProcessId(bpmnProcessId).latestVersion().send();
    // could put the future somewhere and eventually wait for its completion
    instancesCreating++;
}
