Data Flow Item
Teminology
DataFlowItem is used for model a more fined-grained data exchange.
We could follow for example the following convention :
| Protocol | DataFlow | DataFlowItem |
|---|---|---|
| API | A service exposed through a Swagger | An operation of the service |
| File | A fhysical File | A substructure in the File |
| Event | A topic | An Event in the topic |
Example
Data flow (topic /EVT/CUSTOMER) is used by two Data Flow Item (typically Kafka Events) :
- A DataFlowItem (typically Kafka Event) EVT/CUSTOMER/CORE for Customer name, birth date…
- A DataFlowItem (typically Kafka Event) EVT/CUSTOMER/ADDRESS for Customer address
