You want to optimize Kafka disk I/O for a high-throughput topic with many partitions. Which combination of settings is best?

hard📝 Application Q8 of 15

Kafka - Performance Tuning

ASet num.io.threads to 1 and large log.segment.bytes

BDisable log segment rolling and use default io threads

CDecrease num.io.threads and small log.segment.bytes

DIncrease num.io.threads and set moderate log.segment.bytes

Step-by-Step Solution

Solution:

Step 1: Consider high-throughput needs
High throughput with many partitions requires parallel disk I/O and manageable segment sizes.
Step 2: Choose settings for parallelism and segment size
Increasing num.io.threads allows parallel disk access; moderate log.segment.bytes balances file size and rollover frequency.
Final Answer:
Increase num.io.threads and set moderate log.segment.bytes -> Option D
Quick Check:
More io threads + moderate segment size = optimized disk I/O [OK]

Quick Trick: Balance io threads and segment size for throughput [OK]
