Python 基于pykafka简单实现KAFKA消费者

基于pykafka简单实现KAFKA消费者

1．测试环境

pykafka-2.8.0.tar.gz

2．问题描述

使用python-kafka类库实现kafka消费者时，发现程序有时候会自动停止消费，对一些参数进行配置后无果，换成pykafka类库实现，搞定

3．代码简单实现

#-*- encoding:utf-8 -*-

__author__ = 'shouke'

from pykafka import KafkaClient

client = KafkaClient(hosts="127.0.0.1:9092")

# 获取主题

print(client.topics)

topic = client.topics['MY_TOPIC1']

# 获取消费者

consumer  = topic.get_balanced_consumer('MY_GROUP1', auto_commit_enable=True, auto_commit_interval_ms=3000)

for message in consumer:

   if message is not None:

       print(message.offset, message.value)
