The Scalable Go Worker

Description

Here is the translated and optimized English version of your YouTube description, tailored for a global developer audience. Proposed Title: Building a Scalable Poller–Dispatcher–Worker Architecture in Go 🚀 In this video, we dive deep into one of the most critical components of modern backend systems: Background Job Processing. If you are looking for a robust way to handle emails, data synchronization, or event-driven workflows in Go—without your system collapsing under heavy load—this architecture is your answer. What You Will Learn: The 4 Pillars of the Architecture: Job (The Unit of Work): How to design atomic, stateless, and repeatable tasks. Worker (The Executor): Implementing long-running Goroutines that focus solely on execution without worrying about scheduling. Dispatcher (The Orchestrator): Managing service-specific queues and applying Backpressure to prevent Goroutine explosions and memory leaks. Poller (The Decision Maker): The engine that monitors databases or APIs to determine "when" and "what" new jobs need to be triggered. Operational Benefits: Separation of Concerns: Decoupling business logic from execution mechanisms. Lifecycle Management: Implementing Graceful Shutdown to ensure no job is left half-finished. High Testability: Designing systems that allow for deterministic testing of concurrent behaviors without relying on "sleep" timers. This architecture, implemented in the open-source go-worker project, is ideal for ETL systems, microservices, and production-grade scheduled processing. https://github.com/mobintmu/go-worker
