The Apache Wayang community is proud to announce a major milestone in our journey: Apache Wayang has officially graduated from the Apache Incubator and is now a Top-Level Project (TLP) at the Apache Software Foundation (ASF)!
This graduation rewards the community-driven effort, research, innovation, and collaboration of many years. It reflects our shared commitment to open-source development and the growing importance of cross-platform data processing in the broader data ecosystem nowadays. Graduating as an Apache Top-Level Project is an important recognition of the project’s maturity and ensures that Apache Wayang is backed by the full support and oversight of the ASF, guaranteeing openness, meritocracy, and a sustainable development model for years to come.
What Is Apache Wayang?
Apache Wayang (formerly known as Rheem) is a cross-platform data processing system designed to give developers and organizations a unified way to execute pipelines over multiple data processing engines—such as Apache Spark, Apache Flink, PostgreSQL, and more.
Instead of forcing users to choose a single execution backend, Wayang:
- Abstracts data processing engines through a unified API
- Can automatically choose the best execution platform based on workload characteristics
- Optimizes performance by distributing tasks across engines if necessary
- Provides a flexible plugin architecture for integrating new platforms and optimizers
In other words, Wayang enables interoperability across the diverse data landscape and empowers teams to focus on application logic and not infrastructure decisions.
Thank You to Our Community
Apache Wayang wouldn’t exist without its community of developers, users, mentors, and advocates who contributed code, documentation, feedback, and support. A special thanks goes to our Incubator mentors, who helped guide the project through the Apache processes and best practices. Your contributions made this milestone possible, and we’re just getting started.
