# Consumer
from kafka import KafkaConsumer

def main():

    # A message iterator generated, start reading message from the beginning of the topic
    consumer = KafkaConsumer("ctopic", group_id="cg-1", bootstrap_servers=["192.168.229.100:9092", "192.168.229.101:9092"],
                             auto_offset_reset='earliest')

    for msg in consumer:
        topic = msg.topic
        partiton = msg.partition
        # can explained as msg id, starting from 0
        offset = msg.offset
        key = str(msg.key, encoding='utf-8')
        value = str(msg.value, encoding='utf-8')

        print("Topic: "+ topic + "From Partion: " + str(partiton))
        print("Offset: " + str(offset))
        print("Msg key: " + key + " Msg value: " + value)
        print("*"*20)

    consumer.close()

if __name__ == "__main__":
    main()

启动该Consumer，并多次运行Producer, 由于消息的key相同，会被存入同一个partition, 从Consumer端解析出的partition也可以确认
