Synchronous vs. Asynchronous Service Invocations – BPMN Service Task (1)

The BPMN 2.0 Specification provides the Service Task activity allowing users to invoke some application service. In this Blogpost I want to explain the difference between a synchronous and an asynchronous service invocation in Camunda BPM. NOTE: this blogpost covers the topic at an abstract level. If you are looking for concrete, ready-to-use examples, have a look at our quickstart repository:   quickstart on synchronous service invocations  quickstart on asynchronous service invocations Synchronous Service Invocations Let’s start with synchronous service invocations. A synchronous service invocation follows the well-known Request/ Response Pattern: The process engine performs a synchronous request to a service and waits for a response. The characteristic property of this invocation pattern consists in the fact that the process engine…

Introducing an Activity Instance Model to the core Process Engine

(this post was originally part of the 7.0.0-alpha6 release blog post but later extracted into an own post). In 7.0.0-alpha6 we introduced the concept of activity instances and the activity instance tree to the core process engine. This post explains the motivation and gives some insight into the internal implementation. Why do we need an Activity Instance Tree? The activity instance tree contains a node for each activity that is currently active in the process instance. Some activity instances are scopes (such as Embedded Sub processes). Such scope activity instance may have child activity instances: So far so good. But is that not the execution tree provided by the process engine? To some extent yes, but not in  all cases. There are…
