python模拟发送、消费kafka消息

参考文章： https://zhuanlan.zhihu.com/p/279784873

生产者代码：

import traceback

from kafka import KafkaProducer,KafkaConsumer
from faker import Faker

fake=Faker()
# 生产者
kafka_topic = "test_kafka_demo"
kafka_bootstrap_servers = ['xx:9092','xx:9092','xxx:9092']
# 消费者
kafka_topic_group = "test-group-zeze" #消费者群组
def producer(num:int):
    producer = KafkaProducer(bootstrap_servers=kafka_bootstrap_servers)
    phones = [fake.name()+"-"+str(i) for i in range(num)]
    for p in phones:
        msg = bytes(p, encoding='utf-8')
        # print("生成消息",msg)

　　　　　　#同一个key的消息会被自动分配到同一个分区
        future=producer.send(kafka_topic, key=b"test",value=msg)
　　　　　　#加了监听事件是否成功发送后，执行速度很慢，所以这里去掉了
        # try:
        #     future.get(timeout=2)
        # except Exception as e:
        #     traceback.print_stack()
    print("成功生产{}条消息".format(num))
    producer.close()

消费者代码：

from kafka import KafkaConsumer

# 生产者
kafka_topic = "test_kafka_demo"
kafka_bootstrap_servers = ['xx:9092','xx:9092','xx:9092'] #xx为对应的ip地址
# 消费者
kafka_topic_group = "test-group-zeze" #消费者群组

def consumer():
    consumer = KafkaConsumer(kafka_topic,group_id=kafka_topic_group,bootstrap_servers=kafka_bootstrap_servers)

    for message in consumer:
        print ("开始消费：","%s:%d:%d: key=%s value=%s" % (message.topic, message.partition,
                                              message.offset, message.key,
                                              message.value))

    # consumer.close()

亲测单机生产10w消息耗时20秒内，单线程

消费者没记录耗时，但是也非常快，kafka性能确实牛
