Kafka different ways to consume messages - when to use which one?

Question

I am new to Messaging as well as Aapache kafka.I am confused on which Consumer API to use in which scenario,I saw that there are two client libraries available

kafka_2.11_0.10.11 and kafka-clients-0.10.1.1

The first one uses somewhat

ConsumerConnector consumer = kafka.consumer.Consumer.createJavaConsumerConnector...
consumer.createMessageStreams...

and in second one

 KafkaConsumer<K,V> consumer = new KafkaConsumer<>(properties);
 consumer.subscribe(...

Does these two API server different purposes?

Answer 1

You should use the implementation in the kafka-clients library. The implementation in the main Kafka library are remains from an older implementation and will likely be removed in future releases.
