Core services
- Control plane for APIs and compute orchestration
- Pageserver for versioned page reads and ancestry traversal
- WAL service for durable WAL handling and quorum mode
- Postgres-compatible computes using the Rowkai storage manager
Architecture
Compute and storage are separated so branching stays fast and tenant infrastructure stays legible.
Rowkai uses a Neon-style architecture with stateless computes, shared page storage, WAL ingestion, and a control plane that manages tenants, timelines, branches, and compute lifecycle.
Branching model
- Instant branch creation with metadata-only writes
- Copy-on-write page storage
- Timeline ancestry traversal
- Nested branches for preview, support, and rollout paths
Why it matters
This makes Rowkai one system for multitenant Postgres-compatible infrastructure, instead of a stack of custom snapshot jobs, restore scripts, and separate GraphQL glue.
