Apache Gravitino is an open-source metadata lake that brings together metadata from file stores, relational databases and event streams in one catalogue. It manages access control and governance across these sources and works with engines such as Spark, Trino and Flink. Data and platform teams use it to discover datasets and apply consistent policies. It is software that organisations install and operate themselves, licensed under the Apache License, Version 2.0.
The project is maintained under the Apache Software Foundation, a U.S. 501(c)(3) non-profit organisation. Because the code is Apache 2.0 licensed and runs on infrastructure the operator controls, no vendor-operated cloud or foreign parent company sits between the metadata and the organisation. The project's website describes no vendor-operated cloud service. Exposure to non-European legal regimes therefore depends on where the operator deploys it. For a European organisation, self-hosting in an EU data centre keeps control over where catalogue metadata is stored.
