hard📝 Application Q8 of 15

Kafka - Event-Driven Architecture

AUse a single producer and consumer to avoid complexity

BProcess orders synchronously in a single application without Kafka

CUse multiple producers sending orders to a Kafka topic and multiple consumers processing orders independently

DStore orders in a database and poll it periodically instead of Kafka

Step-by-Step Solution

Solution:

Step 1: Identify event-driven scaling principles
Multiple producers and consumers allow parallel processing and load distribution.
Step 2: Evaluate options for handling spikes
Independent consumers can scale out to handle more orders during spikes.
Final Answer:
Use multiple producers sending orders to a Kafka topic and multiple consumers processing orders independently -> Option C
Quick Check:
Parallel producers and consumers = scalable spikes [OK]

Quick Trick: Multiple producers and consumers handle spikes best [OK]
