What is it?

SeaTunnel is a distributed data integration tool for moving large volumes of data between sources and sinks. It offers over 160 connectors covering databases, data warehouses and other systems, and supports real-time synchronization, change data capture (CDC), and full-database synchronization.

Jobs are defined through configuration, and SeaTunnel can run them on its own Zeta Engine or on Apache Flink or Apache Spark. The project also includes a distributed snapshot mechanism intended to keep synchronized data consistent, along with JDBC multiplexing and log parsing to reduce connection overhead when syncing many tables.

Beyond structured text, SeaTunnel can handle unstructured data such as video, images and binary files, with guidance provided in its documentation.
