Step-by-Step Solution
Solution:
Step 1: Understand linger.ms = 0 effect
Withlinger.msset to 0, the producer sends batches immediately without waiting to fill them.Step 2: Effect of large batch.size with zero linger
Even if batch.size is large, batches may be smaller because producer does not wait to accumulate more messages.Final Answer:
Producer sends batches immediately, possibly smaller than batch.size -> Option BQuick Check:
linger.ms=0 means no wait, immediate send [OK]
Quick Trick: linger.ms=0 sends batches immediately [OK]
Common Mistakes:
MISTAKES- Thinking producer waits to fill batch with linger.ms=0
- Assuming error occurs with large batch.size
- Confusing batch size with compression
