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

Suspend fetching from the requested partitions.

In contrast, the once the given completionHandler is called the #batchHandler(Handler) will not see messages from the given topicParations.

Parameters

topicPartitions - topic partition from which suspend fetching

completionHandler - handler called on operation completed
