You want to optimize a Kafka consumer for high throughput but low latency. Which combination of settings is best?

hard📝 Application Q15 of 15

Kafka - Performance Tuning

ASet both <code>max.poll.records</code> and <code>fetch.min.bytes</code> to high values

BSet <code>max.poll.records</code> low (e.g., 10) and <code>fetch.min.bytes</code> high (e.g., 1048576)

CSet <code>max.poll.records</code> high (e.g., 1000) and <code>fetch.min.bytes</code> low (e.g., 1)

DSet both <code>max.poll.records</code> and <code>fetch.min.bytes</code> to low values

Step-by-Step Solution

Solution:

Step 1: Understand throughput and latency tradeoff
High max.poll.records allows processing many records per poll, increasing throughput.
Step 2: Understand fetch.min.bytes effect on latency
Low fetch.min.bytes means the consumer fetches data quickly without waiting for large batches, reducing latency.
Step 3: Combine settings for desired effect
High batch size with low fetch size balances high throughput and low latency.
Final Answer:
Set max.poll.records high (e.g., 1000) and fetch.min.bytes low (e.g., 1) -> Option C
Quick Check:
High batch + low fetch.min.bytes = throughput + low latency [OK]

Quick Trick: High max.poll.records + low fetch.min.bytes = best balance [OK]
