hard📝 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Understand large message processing needs
Large messages require waiting for enough data to reduce latency and improve throughput.Step 2: Evaluate settings for latency and throughput
Increasing fetch.min.bytes and fetch.max.wait.ms lets consumer wait for larger batches, while moderate max.poll.records avoids processing overload.Final Answer:
Increase fetch.min.bytes and fetch.max.wait.ms; keep max.poll.records moderate. -> Option DQuick Check:
Wait for bigger batches, moderate record count for efficiency [OK]
Quick Trick: Wait for bigger batches, moderate max.poll.records [OK]
Common Mistakes:
MISTAKES- Setting max.poll.records too high causing delays
- Decreasing fetch.max.bytes limiting batch size
- Setting max.poll.records to 1 reducing throughput
