Kafka - Performance Tuning

Given this Kafka producer config snippet:

props.put("batch.size", 16384);
props.put("linger.ms", 5);
props.put("acks", "all");

What is the expected effect on message sending?

AMessages batch up to 16KB or wait 5ms before sending, with full acknowledgment.

BMessages are compressed automatically before sending.

CMessages are sent immediately without batching.

DProducer waits for only one replica acknowledgment.

Step-by-Step Solution

Solution:

Step 1: Analyze batch.size and linger.ms
Batch size 16384 bytes means messages batch up to 16KB or linger 5ms before sending.
Step 2: Understand acks setting
acks=all means producer waits for all replicas to confirm, ensuring durability.
Final Answer:
Messages batch up to 16KB or wait 5ms before sending, with full acknowledgment. -> Option A
Quick Check:
batch.size + linger.ms + acks=all = Messages batch up to 16KB or wait 5ms before sending, with full acknowledgment. [OK]

Quick Trick: Batch size + linger.ms controls send timing, acks controls durability [OK]
