Python同时使用KafkaConsumer和Producer是指在Python编程语言中,同时使用KafkaConsumer和KafkaProducer两个模块来实现对Kafka消息队列的消费和生产操作。 Kafka是一种高吞吐量、分布式的发布订阅消息系统,常用于构建实时流数据管道和大数据处理应用。KafkaConsumer用于从Kafka主题中消费消息,而KafkaProducer用于向Kafka主题中发送消息...
Consumer The following example creates a consumer with the<my-subscription>subscription name on the<c8globals or c8locals>.<my-topic>topic or multiple topics with global either local distribution. For example: KafkaConsumer("c8globals.topic-1", "c8locals.topic-2", bootstrap_servers=...)....
After that, all that's needed is that you pass an extra parameteruse_rdkafka=Truetotopic.get_producer(),topic.get_simple_consumer(), ortopic.get_balanced_consumer(). Note that some configuration options may have different optimal values; it may be worthwhile to consult librdkafka'sconfigurati...
Hi, I took the example script with both producer & consumer. The producer code looks like this: class Producer(threading.Thread): daemon = True def run(self): producer = KafkaProducer(value_serializer=lambda v: json.dumps(v).encode('utf-...
