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 configuredpartition-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. CallingcommitSyncon the passed akka.kafka.RestrictedConsumer is available.This complements the methods of Kafka's ConsumerRebalanceListener with an
onStopcallback which is called beforeConsumer.close.
