Kafka - Event-Driven Architecture

AService A retries sending 'OrderCreated' automatically.

BNo 'PaymentProcessed' event is emitted, but Service A continues normally.

CThe orchestrator triggers Service B again immediately.

DAll services stop until Service B recovers.

Step-by-Step Solution

Solution:

Step 1: Understand choreography independence
Services act independently; if Service B crashes, it won't emit events but others keep running.
Step 2: Check other options
There is no orchestrator to retry or stop all services in choreography.
Final Answer:
No 'PaymentProcessed' event is emitted, but Service A continues normally. -> Option B
Quick Check:
Choreography services run independently [OK]

Quick Trick: In choreography, one service failure doesn't stop others [OK]

Common Mistakes:

Assuming automatic retries without orchestration
Thinking all services stop on one failure
Confusing choreography with orchestration
