Python测试Kafka集群(pykafka)

生产者代码：

# -* coding:utf8 *-
from pykafka import KafkaClient  

host = 'IP:9092, IP:9092, IP:9092'
client = KafkaClient(hosts = host)  

print client.topics  

# 生产者
topicdocu = client.topics['my-topic']
producer = topicdocu.get_producer()
for i in range(100):
    print i
    producer.produce('test message ' + str(i ** 2))
producer.stop()

消费者代码：

# -* coding:utf8 *-
from pykafka import KafkaClient  

host = 'IP:9092, IP:9092, IP:9092'
client = KafkaClient(hosts = host)  

print client.topics  

# 消费者
topic = client.topics['my-topic']
consumer = topic.get_simple_consumer(consumer_group='test', auto_commit_enable=True, auto_commit_interval_ms=1,
                                     consumer_id='test')
for message in consumer:
    if message is not None:
        print message.offset, message.value
