io.smallrye.reactive.messaging.kafka.commit

Class KafkaLatestCommit

java.lang.Object

io.smallrye.reactive.messaging.kafka.commit.ContextHolder

io.smallrye.reactive.messaging.kafka.commit.KafkaLatestCommit

All Implemented Interfaces:

KafkaCommitHandler

public class KafkaLatestCommit
extends ContextHolder
implements KafkaCommitHandler

Will commit the record offset received by the Kafka consumer (if higher than the previously committed offset). This offset may be greater than the currently ACKed message.

This handler is the default when `enable.auto.commit` is `false`. This strategy provides at-least-once delivery if the channel processes the message without performing any asynchronous processing.

This strategy should not be used on high-load as offset commit is expensive.

To use set `commit-strategy` to `latest`.
