Kafka - Performance Tuning

A Kafka producer is not sending messages as expected. The config is:

{"batch.size": 16384, "linger.ms": -1}

What is the issue?

A"batch.size" is too small to send messages

B"linger.ms" cannot be negative; it causes config error

CProducer requires "linger.ms" to be zero for batching

DNegative "linger.ms" means immediate send, so no issue

Step-by-Step Solution

Solution:

Step 1: Check valid range for linger.ms
linger.ms must be zero or positive; negative values are invalid.
Step 2: Identify effect of invalid linger.ms
Negative linger.ms causes configuration error, preventing message sending.
Final Answer:
"linger.ms" cannot be negative; it causes config error -> Option B
Quick Check:
linger.ms negative invalid = B [OK]

Quick Trick: linger.ms must be zero or positive [OK]
