Real-Time Streaming with Kafka

Kafka handles massive real-time data streams. Powers IoT, ML pipelines, and event-driven architectures.

Setup

from kafka import KafkaProducer, KafkaConsumer

producer = KafkaProducer(bootstrap_servers=['localhost:9092'])
producer.send('sensor-data', b'{"temp": 23.5, "timestamp": 1234567890}')

consumer = KafkaConsumer('sensor-data', auto_offset_reset='earliest')
for message in consumer:
    process_sensor_data(message.value)
