Scio is developed and maintained by an infrastructure team at Spotify. It is the preferred API for both batch and streaming data processing on Google Cloud Dataflow at Spotify and many other companies. The project wouldn't have been successful without contributions from all the external users.
Feel free to discuss issues in our Gitter room or Google Group first.
Don't hesitate to create GitHub issues for bugs, feature requests, or questions. When reporting a bug, it would help to include a small, reproducible code snippet or unit test.
Before opening a pull request, make sure sbt scalastyle test runs successfully. It's usually a good idea to keep changes simple and small. Please also be consistent with the code base and our style guide.
If there is already a GitHub issue for the task you are working on, leave a comment to let people know that you are working on it. If there isn't already an issue and it is a non-trivial task, it's a good idea to create one (and note that you're working on it). This prevents contributors from duplicating effort.
You can contribute to Scio documentation by editing the wiki pages. You can also help us improve the API documentation. Run sbt make-site in the project root. The generated site is under target/site/index.html.
