Kafka - Performance Tuning

A Kafka configuration has log.segment.bytes=0. What is the problem?

AInvalid segment size disables log segment creation

BSegments will roll over every 0 bytes, causing errors

CKafka will use default segment size ignoring 0

DThis setting disables disk I/O threads

Step-by-Step Solution

Solution:

Step 1: Understand zero segment size effect
Setting segment size to 0 is invalid and prevents proper log segment creation.
Step 2: Evaluate other options
Rolling over every 0 bytes is impossible, Kafka does not silently ignore zero, and disk I/O threads are unrelated.
Final Answer:
Invalid segment size disables log segment creation -> Option A
Quick Check:
log.segment.bytes=0 is invalid and breaks log segments [OK]

Quick Trick: Segment size must be positive non-zero [OK]
