Tasker – Distributed HTTP Task Scheduler

Tasker is a lightweight, distributed job scheduler designed to handle HTTP tasks asynchronously. Built with Go, it leverages a microservices architecture to efficiently manage task queuing, execution, and status tracking.

🧩 Architecture Overview

Tasker comprises two decoupled microservices:

1. API Server
   Handles incoming task submissions via HTTP, persists them to a PostgreSQL database, and provides endpoints to query task statuses.

2. Agent Worker
   Continuously polls the database for new tasks, executes them concurrently, and updates their statuses upon completion.

• Concurrent task processing with Go routines
• RESTful API for task management
• PostgreSQL integration for reliable persistence
• Modular microservices architecture
