EDA scenario
This scenario shows how the event processing business pattern for event-driven architecture integration described in Chapter 1 can be implemented.
Implementing the event processing business pattern
As shown in the following diagram, the event processing business pattern can be implemented using a Complex Event Processing (CEP) engine, which is controlled by an ESB.
Trigger:
- An event occurs and is placed in a queue by the source system.
Primary flow:
- An event-driven consumer building block removes the messages or events from the queues using an appropriate JMS adapter, and forwards them to the CEP engine.
- The CEP engine uses a specific query ...
