assign

abstract fun assign(partitions: MutableSet<TopicPartition>): KafkaReadStream<K, V>

Manually assign a set of partitions to this consumer.

Parameters

partitions - partitions which want assigned

Return
current KafkaReadStream instance

abstract fun assign(partitions: MutableSet<TopicPartition>, completionHandler: Handler<AsyncResult<Void>>): KafkaReadStream<K, V>

Manually assign a set of partitions to this consumer.

Due to internal buffering of messages, when reassigning the old set of partitions may remain in effect (as observed by the #handler(Handler) record handler)} until some time after the given completionHandler is called. In contrast, the once the given completionHandler is called the #batchHandler(Handler) will only see messages consistent with the new set of partitions.

Parameters

partitions - partitions which want assigned

completionHandler - handler called on operation completed

Return
current KafkaReadStream instance
