Step-by-Step Solution
Solution:
Step 1: Understand batch.size and linger.ms effects
Larger batch.size and higher linger.ms allow Kafka to batch more messages, improving throughput.Step 2: Consider num.io.threads impact
Increasing num.io.threads allows more parallel I/O operations, helping handle higher load.Step 3: Evaluate options
Increase batch.size, increase linger.ms, and increase num.io.threads increases all three to improve throughput; others reduce some settings, which lowers throughput.Final Answer:
Increase batch.size, increase linger.ms, and increase num.io.threads -> Option AQuick Check:
Increase batch, linger, and I/O threads = A [OK]
Quick Trick: Increase batch size, linger time, and I/O threads for throughput [OK]
Common Mistakes:
- Reducing batch size or linger.ms when throughput is needed
- Decreasing I/O threads limits parallelism
- Mixing increase and decrease incorrectly
