python kafka多线程消费数据

1、打印每个线程id，满足预期，开启了8个线程，每个线程号都不一样；

 

2、查看kafka状态，也能满足预期，每个分区的消费者id都是不一样的，下面第二个图是开启一个消费者时的状态，每个分区的消费者id都是相同的；对比之下能满足需求；

 

 

 

 

3、相关代码如下：

from kafka import KafkaConsumer
import time, threading
from concurrent.futures import ThreadPoolExecutor


class ThreadKafka(object):

    def __init__(self):
        self.threadPool = ThreadPoolExecutor(max_workers=8, thread_name_prefix="threading_")
        self.hosts = ["ip:port", "ip:port", "ip:port"]

    def operate(self):
        consumer = KafkaConsumer("topic_name", bootstrap_servers=self.hosts, group_id="group_id_name")
        print(threading.current_thread().name)
        for i in consumer:
            print(i)
            time.sleep(1)

    def main(self):
        for i in range(8):
            self.threadPool.submit(self.operate, )


if __name__ == '__main__':
    cla = ThreadKafka()
    cla.main()
