Kafka - Performance Tuning

Given this Kafka producer config:

{"batch.size": 32768, "linger.ms": 20}

What is the expected effect on message sending?

AMessages are compressed before sending

BMessages are sent in larger batches with a slight delay

CBatch size is ignored and messages send one by one

DMessages are sent immediately without batching

Step-by-Step Solution

Solution:

Step 1: Understand batch.size effect
Batch size sets max bytes per batch; larger means more messages grouped.
Step 2: Understand linger.ms effect
Linger.ms adds delay to wait for more messages before sending batch.
Final Answer:
Messages are sent in larger batches with a slight delay -> Option B
Quick Check:
Batch size + linger.ms effect = D [OK]

Quick Trick: Batch size + linger.ms controls batch sending timing [OK]
