Faust looks really cool with its native Python implementation. How does this compared with Apache Beam or Google's Dataflow as they have recently rolled out their Python SDK?
Faust is a library that you can import into your Python program, and all it requires is Kafka. Most other stream processing systems require additional infrastructure. Kafka Streams has similar goals, but Faust additionally enables you to use Python libraries and perform async I/O operations while processing the stream.
