+## Use a PostgreSQL database for metadata **(BETA)**
+
+WARNING:
+The metadata database is in early beta for self-managed GitLab instances.
+
+By default, the container registry uses object storage to persist metadata
+related to container images. This method to store metadata limits how efficiently
+the data can be accessed, especially data spanning multiple images, such as when listing tags.
+By using a database to store this data, many new features are possible, including
+[online garbage collection](https://gitlab.com/gitlab-org/container-registry/-/blob/master/docs-gitlab/db/online-garbage-collection.md)
+which removes old data automatically with zero downtime.
+
+This database works in conjunction with the object storage already used by the registry, but does not replace object storage.
+You must continue to maintain an object storage solution even after migrating to a metadata database.
+
+The metadata database is already in use on GitLab.com, and is now available as a beta feature
+for self-managed GitLab instances.
+
+### Known Limitations
+
+- No support for online migrations.
+- Geo Support is not confirmed.
+- Registry database migrations must be ran manually when upgrading versions.

+Instructions on how to migrate to the database may be found in the [feedback issue](https://gitlab.com/gitlab-org/gitlab/-/issues/423459) for the beta period.
