Python测试Kafka集群(pykafka)实例

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
