QueueForge-Backend

Vision

QueueForge is a backend system designed to reliably accept, process, retry, and track background jobs with a strong focus on failure handling and observability.

Goals

• Accept jobs via a REST API
• Process jobs asynchronously using background workers
• Persist job state and execution history
• Retry failed jobs using controlled retry strategies
• Expose system health and job status for observability

Non-Goals

• No user authentication or authorization
• No UI or dashboard
• No external integrations in v1
• No premature optimization or scaling

High-Level Architecture

QueueForge follows a layered architecture to enforce separation of concerns and maintain testability.

Layers

• API Layer

  • Exposes REST endpoints
  • Handles HTTP concerns (routing, validation, status codes)
  • Contains no business logic

• Application Layer

  • Contains use cases and business rules
  • Orchestrates job lifecycle (enqueue, start, retry, complete, fail)
  • Depends only on domain abstractions

• Domain Layer

  • Contains core domain entities and rules
  • Framework-agnostic
  • Represents the job and execution lifecycle

• Infrastructure Layer

  • Implements persistence, background workers, and external concerns
  • Provides concrete implementations for application interfaces
  • Replaceable without affecting business logic
