RabbitMQ - Performance Tuning

Which effect does setting a low prefetch count have on a RabbitMQ consumer?

AConsumer processes fewer messages concurrently, improving fairness

BConsumer receives all messages at once, increasing throughput

CConsumer automatically acknowledges messages faster

DConsumer deletes messages from the queue immediately

Step-by-Step Solution

Solution:

Step 1: Analyze low prefetch impact
A low prefetch count means the consumer gets fewer messages at a time.
Step 2: Understand concurrency and fairness
This limits concurrency but allows other consumers to get messages, improving fairness.
Final Answer:
Consumer processes fewer messages concurrently, improving fairness -> Option A
Quick Check:
Low prefetch = fewer concurrent messages [OK]

Quick Trick: Low prefetch means fewer messages processed at once [OK]
