Scope
We run GitLab’s datastores and data movement as internal services. Every system here has an owner who answers for its SLOs, capacity, cost, and upgrades. We don’t write product queries or business logic: the Event Platform writes into this layer, and Intelligence reads from it.
Teams
- Data Storage: ClickHouse and GitLab’s analytics datastores.
- Message Queue and Replication/CDC: NATS and Siphon, the messaging backbone and change data capture.
Message Queue and Replication/CDC
