Bytewax

Project2.1K

Build Python dataflows that transform and analyze event streams, with stateful operators and connectors.

What you can build

  • Build a Kafka consumer flow that uses stateful processing to suppress repeated order IDs and sends accepted events to Redis.
  • Build a flow that counts WebSocket events in event-time windows and writes service windows that cross your chosen threshold to S3.
  • Build a join between order and inventory events keyed by product, then emit records whose quantities do not match to a downstream sink.
  • Build a custom connector for a vendor source and transform its records into a consistent event shape for later dataflow operators.
  • Build a regression harness that feeds representative events through a flow with TestingSource and checks outputs for changed business rules.

Try this prompt

Build a small Python Bytewax dataflow that reads order events from Kafka, filters duplicate order IDs using stateful processing, and sends accepted events to Redis. Include a focused test using TestingSource and explain the input and output shapes. Use documented Bytewax APIs and connector guidance rather than guessing interfaces. Keep the flow's business logic separate from connector setup, and state any configuration the reader must supply. Do not discard or overwrite source data as part of the workflow.

Get started

  1. Install and explore

    Install Bytewax from PyPI as documented in the README, then follow its Quick Start example to define and run a local dataflow.

  2. Choose connectors

    Review the documented built-in connectors and connector API. For an unsupported source or sink, consult the official custom-connectors guide before designing an adapter.

  3. Test and deploy

    Use TestingSource and the testing guide for flow tests. For containers or Kubernetes deployment, follow the corresponding official deployment guides; infrastructure is not included.

License & notes

Apache-2.0Bytewax is Apache-2.0 and has no model requirement. Budget for the compute and hosting needed to run your flows, plus any separately paid sources, sinks, or infrastructure. Kubernetes and other infrastructure may add costs. The README identifies a commercially licensed Bytewax Platform; it does not provide pricing. Preserve Apache-2.0 notices and follow its terms when redistributing the software or modified copies.

  • Bytewax is community-maintained; the README says the original core team stepped back from day-to-day maintenance in May 2025.
  • Running flows requires compute and hosting, and external connectors or infrastructure may have separate costs.
  • The README points to a commercially licensed Bytewax Platform; its terms and pricing are not detailed in the supplied material.
