Multi-tenant OKR platform with Postgres RLS, partitioned audit logs, and real-time SSE dashboards.
Building multi-tenant SaaS is easy until you need proper data isolation, audit logging, and real-time updates. Most solutions either sacrifice security for convenience or become unmaintainable.

OpenTelemetry → Grafana| Decision | Choice | Why |
|---|---|---|
| Multi-tenancy | Postgres RLS | Row-level security at the database layer. Can't accidentally leak data. |
| Audit logs | Partitioned tables | Time-based partitioning for efficient queries and retention policies. |
| Real-time | SSE over WebSocket | Simpler, works through proxies, sufficient for dashboard updates. |
