Event Integration

CPS Core and CPS Temporal are integrated with an event driven architecture. Integration between these two components is event notification based.

For each data modification handled by CPS Core,

• CPS Core is publishing, to a dedicated Kafka topic, an event representing the data configuration or state.

• CPS Temporal is listening to the same topic for the event and is responsible to keep track of all data over time.

Refer to CPS Temporal Modeling for more details on the event structure.
