Optimized service interaction patterns

The following service interaction patterns are typically used to send requests to external services, systems, or both.
  • Request/Response
  • Fire and forget

These scenarios need the FTM objects, which are shown in the following figures, to be created in the FTM database. The lifecycle of these objects needs to be managed by the generic FSM model:

Figure 2. Fire and forget

While the creation and lifecycle management of these objects provides high levels of process visibility, this visibility comes with a performance cost. Beginning with FTM V2.1, you can configure whether these objects are created and whether full lifecycle management is enabled for the objects that are created.
