Apache SeaTunnel is an open-source data integration tool from the Apache Software Foundation, aimed at data engineers who move data between databases, streaming systems, lakehouses and object storage. It supports batch, streaming and change data capture pipelines, with schema evolution and checkpoint-based fault tolerance. Pipelines are declared in a configuration file and can run on the Zeta, Apache Flink or Apache Spark engines. The project describes itself as an Apache top-level project and is distributed as software that organisations install and operate themselves.
The Apache Software Foundation is a US non-profit organisation (501(c)(3)) with a mailing address in Wilmington, Delaware, so it falls under US law. The code is licensed under Apache License 2.0. Because the project does not describe a hosted service of its own, the place of installation and the chosen support providers determine sovereignty in practice. A European organisation can run SeaTunnel inside its own infrastructure and choose its own service providers.
