    The API is new and may change in further releases.

    The API is new and may change in further releases.

    Allows the user to execute user code when Kafka rebalances partitions between consumers, or an Alpakka Kafka consumer is stopped. Use with care: These callbacks are called synchronously on the same thread Kafka's poll() is called. A warning will be logged if a callback takes longer than the configured partition-handler-warning.

    There is no point in calling Committable's commit methods as their committing won't be executed as long as any of the callbacks in this class are called. Calling commitSync on the passed akka.kafka.RestrictedConsumer is available.

    This complements the methods of Kafka's ConsumerRebalanceListener with an onStop callback which is called before Consumer.close.

    Utility class for producing to Kafka without using Akka Streams.
