Kafka streams: consumer poll timeout has expired

[kennylam91]

Describe the bug

Our service is using extension quarkus-kafka-streams@3.8.5 to handle kafka messages. Everything was working fine until we added some new logic which took some more time for each message. The service didn't receive or consume any kafka messages.
We found this log before the service stopped working:
2024-11-15T10:55:30.336+0000 WARN [or.ap.ka.cl.co.in.ConsumerCoordinator] (kafka-coordinator-heartbeat-thread | ...) [Consumer clientId=d48eb33d-243e-429a-9036-a990faf0da9c-StreamThread-2-consumer, groupId=...] consumer poll timeout has expired. This means the time between subsequent calls to poll() was longer than the configured max.poll.interval.ms, which typically implies that the poll loop is spending too much time processing messages. You can address this either by increasing max.poll.interval.ms or by reducing the maximum size of batches returned in poll() with max.poll.records.

But actually the service was not down, it just stopped consuming messages.
I've search for this error and the results said that when this issue consumer poll timeout has expired happens, the consumer would be kicked out of consumer group. Is that true? How can we deal with it?
The log level WARN is also a little bit confusing.

Any help or suggestion is appreciated, thanks in advance.

You can increase the max.poll.timeout.ms of your streams application.
In any case if the Kafka Streams state is other than running or rebalancing we do put the health check to down.

In missed poll timeout however, I am not sure how Kafka Streams behaves, it may go to rebalancing state and stay there forever because its consumer is kicked out of the group.

Hope this helps.

I've tried overriding the related configurations as following, but they have no effects.

kafka-streams.max.poll.records=400
kafka-streams.max.poll.interval.ms=600000

I guess the reason is they are not defined/declared in StreamsConfig.class.
