Alaister YoungandAlaister Young 928049ce2c [FE-3717] feat(studio): Multigres cluster topology diagram (#49298)
Adds an infrastructure/topology diagram for High Availability
(Multigres) projects showing the real cluster topology — gateway tier,
shard group, and the primary + read replicas inside it — on both the
project homepage and the database/replication page, replacing the
primary-only view and the "Replication unavailable" empty state.

Addresses
[FE-3717](https://linear.app/supabase/issue/FE-3717/show-replicas-in-replication-diagram).

**Added:**

- `data/ha-admin/` — read-only queries for the mgmt-api
`/ha-admin/v1/{gateways,poolers,cells,databases}` multiadmin passthrough
(ported from `bobbie/ha-stub`, re-authored to `queryOptions`). Responses
are validated with zod at the fetch boundary (all fields optional per
proto3 zero-value omission; enum-shaped fields stay plain strings so new
proto values degrade gracefully); malformed payloads surface through the
diagram's error fallback.
- `HaTopology.utils.ts` — pure topology mapper (+ 26 unit tests): shard
grouping, primary identified via `routingState.role` (deprecated `type`
as fallback) with **failover-safe election** — when the outgoing and
incoming primary briefly both claim `ROUTING_ROLE_PRIMARY`, the highest
routing rule (coordinator term, leader subterm) wins, matching the
multigateway's own election — plus status mapping onto the existing
Healthy / Coming up / Going down / Unhealthy vocabulary, and an AZ
formatter for `id.cell` that degrades to the raw cell name.
- HA diagram nodes/edges: `Multigateway` card, shard group box with
header pill (`Shard 1`, `Automatic failover` + tooltip), `Primary
Database` card styled like the standard diagram's — neutral border,
green icon chip (with the standard CPU / Disk / RAM footer — connections
omitted until their meaning through the multigateway is confirmed),
`Read Replica` cards, and the standard animated replication edges
(status lives on the card badges). Poolers and gateways poll every 30s
without re-running layout (topology projection + structural sharing).
Drag-to-pan works through the shard group box, and the metrics footer's
skeleton matches the loaded row height so the card doesn't shift.
- Accessibility: the failover tooltip trigger is a keyboard-focusable
button, status badges sit in stable `role="status"` live regions, the
region flag is decorative (`alt=""`), and the edge dash/spinner
animations respect `prefers-reduced-motion` (applied to the pipelines
diagram's edges too).
- Fallbacks: `AlertError` ("Failed to retrieve cluster topology") when
either ha-admin query errors, and a "Cluster topology unavailable" empty
state when the topology comes back empty — never a half-rendered
diagram.

**Changed:**

- `InstanceConfiguration` is now topology-source-aware: it branches
internally on `useHighAvailability()`, so both surfaces (homepage
`TopSection` and the replication page) get the right diagram with no new
wiring. The two-pass measured dagre layout moved into a shared
`DiagramFlow`; `nodeTypes`/`edgeTypes` are module-level consts.
- `getEdgeVisual` + the mid-edge icon chip lifted out of
`ReplicationDiagram/Edges.tsx` into
`components/ui/ReactFlow/EdgeVisual.tsx` so both diagrams derive edge
icon + line style from one state object (no behavior change for the
pipelines diagram). The primary card's CPU/Disk/RAM footer is likewise
extracted into a shared `ComputeMetricsFooter`.
- Fixes a latent relayout loop inherited from the region-box pattern:
handing React Flow a freshly created (unmeasured) group node on every
layout pass reset `nodesInitialized`, re-triggering the measured pass
and `fitView` forever — which made the diagram snap back to center and
effectively unpannable. The shared `DiagramFlow` now re-attaches known
measurements to group nodes, which also covers the standard diagram's
region boxes.
- Standard diagram: the API Load Balancer → primary edge is now static —
no data flows over it, the line only indicates a relation.
- `database/replication` page: the HA early-return empty state is
replaced by the diagram under a "High Availability cluster topology"
header. Non-HA projects are untouched.

**Intentional deviations from the mock** (for design review):

1. **No per-replica regions** — alpha replicas are one-per-cell inside a
single region, so the mock's `eu-west-1` / `ap-southeast-1` on sibling
replicas would be false. Availability zone per node, region shown once
on the primary.
2. **"Primary Database", not "Main Database"** — matches the string both
existing diagrams already ship, and the same component now renders both
project types.
3. **No collapse chevron on the shard header** — alpha has exactly one
shard; collapsing it would hide the whole diagram. The group box still
ships; add collapse when `shards.length > 1`.
4. **Failover shown on the shard group, not replica cards** — failover
is a cohort property; per-card badging would assert readiness we can't
verify without a per-pooler `/status` fanout.
5. **Standard node/edge styling reused** (per review) — neutral primary
border + green chip and the default animated edges instead of the mock's
green ring and dashed green arrowed edges, keeping the HA and non-HA
diagrams visually consistent.

**Confirmed against a real local Multigres cluster:** cells are named
`cell-1`/`cell-2`/… (not AZ-shaped — the AZ formatter falls back to the
raw cell name as designed); `GET /platform/projects/{ref}/databases`
returns only the primary row for HA projects; and the `/ha-admin`
passthrough returns **each gateway/pooler record once per cell it fans
out to** — the topology mapper dedupes by id, but worth confirming with
@sbc-bobbie whether the backend should dedupe.

**Known alpha limitation:** node health and the "replicating" edge state
derive from the pooler's *topology record*
(`lifecycleStatus`/`servingStatus`), not a live probe — a pooler that
crashes without publishing a terminal state can read as healthy until
the topology evicts its record, and a serving replica with paused replay
still shows a green edge. This matches the existing replication
diagram's semantics (`ACTIVE_HEALTHY` ⇒ animated edge). Live per-pooler
signals (WAL receiver state, replay position) exist on `GET
/poolers/{cell}/{name}/status` but need a per-pooler fanout —
deliberately deferred, noted on `getPoolerStatus`.

**Still to confirm** (doesn't block review): whether the `/ha-admin`
passthrough is deployed to production or staging-only (if staging-only,
this should get a flag before GA).

## To test

Tested end-to-end locally against a real Multigres project
(standard-project regression pass, HA creation flow, error fallback
against real 500s, and full topology + polling + console checks against
live multiadmin data):

- **HA project homepage**: diagram card shows Multigateway → shard box
(`Shard 1`, count badge, `Automatic failover` tooltip) → green-bordered
Primary Database (region, AZ, size) + Read Replica cards (AZ), dashed
green animated edges to healthy replicas. No flow/map toggle for HA.
- **HA project → Database → Replication**: same diagram under a "High
Availability cluster topology" header; no Destinations section; the old
"Replication unavailable…" state is gone.
- **Error path**: if `/ha-admin/v1/*` fails, both surfaces show "Failed
to retrieve cluster topology" with Contact support — no partial diagram.
- **Standard project regression**: homepage diagram (primary card, flow
⇄ map toggle round-trips), replication page (pipelines diagram +
Destinations) all unchanged; zero requests to `/ha-admin/*`.

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
