Database
GitLab is a single application that relies on a single data store (terminology we use in the context of stringent durability requirements, e.g., PostgreSQL as opposed to Redis).
This directive drives GitLab’s product development: while GitLab is SaaS first, it is not SaaS only. In terms of databases, GitLab supports self-managed configurations with a single database cluster, generally through the use of logical databases. Only at scale do we contemplate unfolding the single cluster into multiple ones, as GitLab.
