## English

### Purpose & Overview
Production-grade guidance for designing durable, fault-tolerant background execution pipelines and distributed state machines using Temporal.io, Trigger.dev v3, Inngest, and BullMQ v5. Guarantees execution completion across long-running background tasks, API rate limits, and server crashes.

### Key Capabilities
- **Durable Execution**: Automatic retry, state persistence, and resume after server restarts or network partitions.
- **Saga Pattern Orchestration**: Multi-step distributed transactions with compensation logic for rollback on failure.
- **Rate Limiting & Concurrency**: Controlled worker concurrency, backoff jitter, and per-tenant queue isolation.

```typescript
import { task } from "@trigger.dev/sdk/v3";

export const generateSaaSReport = task({
  id: "generate-saas-report",
  run: async (payload: { tenantId: string }) => {
    // Durable step execution with automatic retries
    const data = await fetchTenantData(payload.tenantId);
    const pdfUrl = await generatePDF(data);
    await sendEmailReport(payload.tenantId, pdfUrl);
    return { success: true, pdfUrl };
  },
});
```

### Deskripsi
Panduan tingkat produksi untuk merancang pipeline eksekusi background yang tahan-gagal (durable execution) dan state machine terdistribusi menggunakan Temporal.io, Trigger.dev v3, Inngest, dan BullMQ v5. Menjamin penyelesaian eksekusi tugas background berdurasi panjang meskipun terjadi server crash atau pembatasan API rate limit.

### Fitur Utama
- **Eksekusi Tahan-Gagal (Durable)**: Retry otomatis, persistensi state, dan kompensasi lanjutan setelah restart server.
- **Pola Saga**: Transaksi terdistribusi multi-langkah dengan logika kompensasi untuk pembatalan saat terjadi kegagalan.
- **Rate Limiting & Konkurensi**: Kontrol konkurensi worker, backoff jitter, dan isolasi antrean per-tenant.
