title: is kafka producer capable of sending multiple messages in a list?
body: <p>In Kafka v 0.8.2, is it still possible/beneficial to send a list of ProducerRecords as a producer as opposed to only a single one at a time? Examining the API it seems like org.apache.kafka.clients.producer.KafkaProducer does not have the ability to send multiple producerRecords using one send call.</p>
  
  <p>However, in the producer under javaapi, it's possible to send a list of keyedMessages. Can someone explain the difference or point me in the right direction? Much appreciated.</p>
