kafka-python-dataclasses

Structured messages for your kafka projects

Kafka is a really complex library and dealing with bytes can be taxing. Use these wonderful structured Kafka classes instead!

Basic consuming:

from dataclasses import dataclass
from kafka_dataclasses import StructuredKafkaConsumer


@dataclass
class MyKafkaMessage:
   value: str


for message in StructuredKafkaConsumer(['my_topic']):
   assert type(message) == MyKafkaMessage

Basic producing:

from dataclasses import dataclass
from kafka_dataclasses import StructuredKafkaProducer


@dataclass
class MyKafkaMessage:
   value: str


StructuredKafkaProducer().send('my_topic', MyKafkaMessage("Hello, world!"))

This works on deeply nested dataclasses as well! In theory it will also work on attrs classes, since the unstructuring library, cattrs, supports attrs out of the box.
