Registry Service

Purpose: Manage provider code, assets, mappings, and data subscriptions. Coordinates with DataHub for validation and symbol discovery.

Run locally

• Docker Compose: docker compose up registry
• Direct: set env vars (DATABASE_URL, QUASAR_SECRET_KEY, provider keys) then uvicorn quasar.services.registry.app:app --reload --port 8080

Configuration

• DATABASE_URL: PostgreSQL/TimescaleDB connection string
• QUASAR_SECRET_KEY: secret for signing or encryption helpers
• Provider credentials: passed through for validation/discovery

Endpoints

• REST (FastAPI) served from quasar.services.registry.app:app
• API schema exposed via FastAPI /docs and /openapi.json

Tests

• Run service tests: pytest tests/services/registry
• Keep API contract changes reflected in tests and docstrings

Notes

• Registry talks to DataHub over HTTP (port 8080 inside Docker).
• Keep schemas in sync with DB migrations under db/schema/.
