What is diff b/w Transient and Durable?

Transient process:
1.Synchronous process is the example of transient process- hence no dehydration activity.
2.No mid process breakpoint activities (Receive, onMessage, onAlarm, Wait)
3.No non-idempotent invoke And No non-blocking invoke
Durable process:
1.Long Running Process Has mid process breakpoint activities (Receive, onMessage, onAlarm, Wait)
2.Has non-idempotent invoke or Has non-blocking invoke
