Bytewax is a Python-first framework for stateful stream processing, designed to simplify complex event-driven applications and online machine learning. It targets Python developers seeking to leverage familiar tools for scalable, distributed dataflow pipelines, offering an alternative to Java-centric frameworks like Flink and Spark.

How It Works

Bytewax employs a dataflow computational model, allowing users to define pipelines using Python operators and connectors. It distinguishes itself with a Pythonic interface, enabling seamless integration with the Python ecosystem. The framework manages distributed state, provides fault tolerance, and supports event-time windowing for advanced analytics. A Rust-based engine underpins its performance, while the waxctl CLI tool facilitates deployment and management across various infrastructures, including Kubernetes.
