Asynckafka
Fast python Kafka client for asyncio. Asynckafka is written in Cython on top of Rdkafka as Kafka driver.
The documentation can be found here.
Features
- Consumer using a balanced group
- Producer
The library was born as a project to learn Cython, right now it only has the basic features implemented, some of the most important missing features are:
- Offset management in the consumer
- Precise partition management
Examples
Simple consumer
How to use a consumer:
consumer = Consumer(
brokers='localhost:9092',
topics=['my_topic'],
group_id='my_group_id',
)
consumer.start()
async for message in consumer:
print(f"Received message: {message.payload}")
Simple producer
How to use a producer:
producer = Producer(brokers="localhost:9092")
producer.start()
await producer.produce("my_topic", b"my_message")
Benchmark
The test was performed in June of 2018 using a single Kafka broker without replication. The purpose of the benchmark was only to have an idea of the order of magnitude of the library's performance under these conditions.
Comparison between asynckafka and aiokafka in production and consumption:

The benchmark used for asynckafka is in benchmark directory while the benchmark used for aiokafka is in its own repository, also in the benchmark folder.
