使用 Kafka-Python 同时发送和使用多个图像

Question

I want to send two or more images simultaneously from Kafka Producer. Is it possibile?

After created a KafkaProducer object kafka_producer and after got frames from two webcam and converted them into bytes using cv2.imencode and tobytes() , I've tried this:

buffer_frame1 = cv2.imencode('jpg', frame1)
buffer_frame2 = cv2.imencode('jpg', frame2)

kafka_producer.send(topic, buffer_frame1.tobytes())
kafka_producer.send(topic, buffer_frame2.tobytes())

I haven't yet implement a KafkaConsumer, but I want to know if this work, and if it don't why and how can I send multiple images simultaneously.

Thanks!

You can encode both bytes objects into another object and then use a serialization library such as pickle (if you must stay within python) to send a single object over the wire.

If you must support other types of languages, JSON is perfectly capable of storing bytes
