Comprehensive and Detailed Explanation
CAP supportsreal-time, event-driven architecturesusing:
D – Message Queues and Event Brokers
This includes:
SAP Event Mesh
Message brokers (AMQP, Kafka via integration adapters)
CAP domain events (emit, on)
Outbox pattern for guaranteed delivery
Event-driven communication between microservices
These features allow:
Loose coupling
Real-time synchronization
Trigger-based data propagation
Integration with SAP S/4HANA event channels
Handling asynchronous workloads
Why the Others Are Incorrect:
A:Database connectivity is synchronous and not event-based.
B:Service connectivity is request/response, not event-driven.
C:Service extensibility allows custom handlers, not messaging.
