What is the default value for max.poll.interval.ms?

• A. 1 minute
• B. 10 minutes
• C. 1 second
• D. 5 minutes

Answer: (D)

The main idea is that max.poll.interval.ms sets how long a consumer can go between poll() calls while processing records in a consumer group. If you let that gap exceed the limit, Kafka treats the consumer as failed and triggers a rebalance, which can disrupt processing. The default value is 5 minutes (300,000 ms). This default strikes a balance between allowing typical processing workloads and keeping the group membership responsive. If your processing takes longer than this, you’d either increase the interval or adjust your design so poll() is called more frequently (for example, by splitting work or offloading processing). Setting it too low can cause unnecessary rebalances for normal workloads.
