Kafka - Performance Tuning

Given the following Kafka configuration snippet:

num.io.threads=2
log.segment.bytes=10485760

What is the expected effect on disk I/O performance?

ATwo network threads and 10 MB max message size

BUnlimited disk I/O threads with 10 GB max segment size

CLimited parallel disk I/O with 10 MB max segment size

DFour disk I/O threads and 1 MB max segment size

Step-by-Step Solution

Solution:

Step 1: Interpret num.io.threads value
Setting num.io.threads=2 means Kafka uses 2 threads for disk I/O, limiting parallelism.
Step 2: Interpret log.segment.bytes value
log.segment.bytes=10485760 equals 10,485,760 bytes, which is 10 MB max segment size.
Final Answer:
Limited parallel disk I/O with 10 MB max segment size -> Option C
Quick Check:
num.io.threads=2 and log.segment.bytes=10MB [OK]

Quick Trick: Check byte values carefully for size units [OK]
