What is the main purpose of increasing the num.io.threads setting in Kafka?

ATo increase the network bandwidth for Kafka brokers

BTo allow more concurrent disk read and write operations

CTo reduce the number of partitions per topic

DTo limit the maximum message size

Step-by-Step Solution

Solution:

Step 1: Understand num.io.threads role
The num.io.threads setting controls how many threads Kafka uses for disk I/O operations.
Step 2: Effect of increasing num.io.threads
Increasing this number allows Kafka to perform more disk read/write operations in parallel, improving throughput.
Final Answer:
To allow more concurrent disk read and write operations -> Option B
Quick Check:
num.io.threads = concurrent disk I/O threads [OK]

Quick Trick: More io threads mean more parallel disk operations [OK]
