Supabase log drains, and see the drains a project already has - #1657
Conversation
…ing drains Discovery lists each project's log drains and keeps a secret-free summary (name, backend, destination host, whether it sends to Maple). A per-project switch creates an OTLP drain to the ingest gateway as a logs-only token source; it replaces polling for that project, and a drain to Maple set up by hand in Supabase blocks it so logs are never stored twice. Migration not generated yet.

Maple review🟢 Confidence 7/10 · likely safe to merge Adds opt-in Supabase OTLP log drains next to hourly drain discovery, with the card switch, request/response schemas and 4 columns. Two toggle paths are wrong: polling can start beside a hand-made Maple drain, and a disable racing an enable is lost.

🟠 Major · Retire managed drains when a reconnect switches… · SupabaseConnectionService.ts:920-929
packages/backend/src/services/integrations/SupabaseConnectionService.ts:920-929
🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winRetire managed drains when a reconnect switches organizations.
When
organizationChangedis true,finalizeConnectstampsremovedAton the old organization's projects. It does not callretireDrains. Later,reconcileProjectsbuildsgoneonly from rows withremovedAt === null. Discovery therefore never reaches these rows.updateProjectalso refuses removed projects withIntegrationsNotFoundError, so the user cannot turn the drains off in Maple.Consequence:
- The old project's Maple drain stays active in Supabase.
- Its
maple_src_token source stays valid.- Logs from a Supabase organization that is no longer connected keep arriving and count against the org's ingest.
- The new grant covers only the new organization, so Maple cannot delete those drains upstream later.
- The token sources are removed only when the org disconnects (the project delete in
disconnectreturnslogDrainSourceId).This code is outside the diff. The new drain lifecycle is what makes it relevant.
Fix:
- Before the transaction, load the old organization's live projects that have a
logDrainIdor alogDrainSourceId. The old grant is still stored at that point.- Delete their drains upstream on a best-effort basis.
- After the switch, delete their token sources, or clear the drain columns in the same
UPDATEand delete those sources inside the transaction.- At minimum, delete the token sources in the transaction. Ingest then rejects the leftover drains.
🛠️ Minimal fix: revoke the old drain sources in the same transaction

Maple review🔴 Confidence 4/10 · risky as written Adds Supabase log-drain discovery to the hourly reconciliation and an opt-in managed OTLP drain per project that replaces polling, with secret-free drain summaries on the card. The guards (pending mark, conditional writes, orphan sweep) hold; the only open issue is a partial metrics write when the logs switch is refused from a stale snapshot.

Maple looks once, an hour after the first deploy that carries the merge. |
A customer wants to keep using Supabase log drains (for their SOC2 retention) and asked whether Maple configures anything on their side. It did not: the integration only polled the logs API, and
log_drain_enabledwas never set. This adds drain support and makes existing drains visible.What changed
GET /v2/projects/{ref}/analytics/log-drains, covered by theanalytics_config:readscope we already request). Each drain is stored as a secret-free summary: name, backend type, destination host / bucket / region, whether it sends to this deployment's ingest, and whether Maple manages it. API keys, auth headers and paths are never stored. A refused listing (Free plan, paused project) keeps the last snapshot and does not fail discovery.maple_src_token source and creates an OTLP drain (http/protobuf, gzip) to the ingest gateway that sends as it. Turning it off deletes the drain and its source; disconnect does the same for every managed drain and never touches the customer's own.
