The registry supports multiple [storage backends](https://gitlab.com/gitlab-org/container-registry/-/blob/master/docs/configuration.md#storage), including Google Cloud Storage (GCS) which is used for the GitLab.com registry. In the storage backend, images are stored as blobs, deduplicated, and shared across repositories. These are then linked (like a symlink) to each repository that relies on them, giving them access to the central storage location. @@ -156,7 +156,7 @@ Running *online* and [*post deployment*](../../../development/post_deployment_mi The registry database will be partitioned from start to achieve greater performance (by limiting the amount of data to act upon and enable parallel execution), easier maintenance (by splitting tables and indexes into smaller units), and high availability (with partition independence). By partitioning the database from start we can also facilitate a sharding implementation later on if necessary. -Although blobs are shared across repositories, manifest and tag metadata are scoped by repository.
