Class KafkaThrottledLatestProcessedCommit

java.lang.Object

io.smallrye.reactive.messaging.kafka.commit.KafkaThrottledLatestProcessedCommit

All Implemented Interfaces:

KafkaCommitHandler

public class KafkaThrottledLatestProcessedCommit
extends Object
implements KafkaCommitHandler

Will keep track of received messages and commit to the next offset after the latest ACKed message in sequence. Will only commit every 5 seconds. This strategy mimics the behavior of the kafka consumer when `enable.auto.commit` is `true`. If too many received messages are not ACKed then the KafkaSource will be marked as unhealthy. "Too many" is defined as a power of two value greater than or equal to `max.poll.records` times 2. This strategy guarantees at-least-once delivery even if the channel performs asynchronous processing. To use set `commit-strategy` to `throttled`.
