Lydtech Consulting Kafka Consumer Group Rebalance Part 1 Of 2 Max.poll.interval.ms: this property specifies the maximum time allowed time between calls to the consumers poll method (consume method in ) before the consumer process is assumed to have failed. the default is 300 seconds and can be safely increased if your application requires more time to process messages. With this library, the frequency of poll is determined by configuration akka.kafka.consumer.poll interval. we say is safe because it will continue polling to avoid the consumer is considered dead even when your processing can't keep up the rate. it's able to do this because kafkaconsumer allows pausing the consumer. **.
Kafka Consumer Concepts Daniel S This topic provides apache kafka® consumer configuration parameters. the configuration parameters are organized by order of importance, ranked from high to low. to learn more about consumers in kafka, see this free apache kafka 101 course. you can find code samples for the consumer in different languages in these guides. In kafka, the max.poll.interval.ms configuration specifies the maximum time a consumer can go without polling the broker for messages. if a consumer exceeds this time, the consumer is considered failed, and the group coordinator will initiate a rebalance of the consumer group, assigning partitions to other consumers in the group. Kafka consumer poll thread. consumers poll brokers periodically using the .poll() method. if two .poll() calls are separated by more than max.poll.interval.ms time, then the consumer will be disconnected from the group. max.poll.interval.ms: (default 5 minutes) the maximum delay between invocations of poll () when using consumer group management. Public class kafkaconsumer<k,v> extends object implements consumer <k,v>. a client that consumes records from a kafka cluster. this client transparently handles the failure of kafka brokers, and transparently adapts as topic partitions it fetches migrate within the cluster. this client also interacts with the broker to allow groups of consumers.
Kafka Consumer Liveliness Kafka consumer poll thread. consumers poll brokers periodically using the .poll() method. if two .poll() calls are separated by more than max.poll.interval.ms time, then the consumer will be disconnected from the group. max.poll.interval.ms: (default 5 minutes) the maximum delay between invocations of poll () when using consumer group management.

Max.poll.interval.ms. this configuration sets the maximum time, in milliseconds, that a kafka consumer can go without polling the kafka cluster for new messages. if a consumer goes longer than the specified time without polling, it will be considered as failed by the kafka cluster, and a rebalance will be triggered. This involves the setting max.poll.interval.ms, which defaults to five minutes. this interval represents the maximum allowed time between two polling actions before the system assumes the consumer.
