# worker
|
|
|
|
## 목적 / 책임
|
|
|
|
데이터 수집, 정규화, backtest 실행, scheduled jobs처럼 오래 걸리거나 비동기적인 작업의 runtime surface를 담당한다. PostgreSQL/Redis integration, worker socket command/query handlers, provider adapters, storage ports, and execution wiring은 이 경계에서 운영 관점으로 다룬다. worker는 client-facing surface가 아니며 API control plane을 통해 제어된다.

|
## 유지할 패턴
|
|
|
|
- Keep external service configuration explicit through `DATABASE_URL` and `REDIS_URL`.
|
|
- Put job orchestration and worker-specific adapters under `services/worker/internal`.
|
|
- Use `packages/domain` for shared business shapes instead of redefining market/backtest concepts.
|
|
- Expose worker-owned command/query/event runtime boundaries to `services/api` through proto-socket when crossing process boundaries.
|
|
- Wire worker execution dependencies in worker entrypoints or worker-internal constructors; API and client must only observe typed availability/errors.
|
|
- Keep store-backed socket surfaces tolerant of unavailable dependencies by returning typed contract errors instead of panicking.
|
|
- Keep provider fixtures secret-free and provider-specific raw payload handling inside provider/marketdata adapters.
|
|
- Keep backtest start asynchronous: socket handlers record or read state synchronously, while execution runs through worker job handlers.

## 다른 도메인과의 경계
|
|
|
|
- **domain-model**: worker consumes domain-model types; it should not make domain-model depend on worker infrastructure.
|
|
- **api**: API may request or observe work; worker owns execution.
|
|
- **operations**: Docker Compose supplies local infrastructure; worker code owns runtime behavior.
|
|
- **contracts**: worker consumes generated ALT protobuf types in socket/contracts adapters; protobuf source remains in `packages/contracts`.
|
|
|
|
## 금지 사항
|
|
|
|
- Do not make worker packages import API internals.
|
|
- Do not hide required infrastructure in package-level globals.
|
|
- Do not store generated contract code in the worker module.
|
|
- Do not expose worker as a direct Flutter/client runtime endpoint.
|
|
- Do not put provider credentials, account numbers, raw tokens, or personal endpoints in worker fixtures, logs, README, or tracked docs.
