Redis Queue and Cron in Go

This tutorial demonstrates building a Go application that uses a task queue and a cron scheduler. It utilizes the `asynq` package for queue management and `robfig/cron` for scheduling. The application consists of four files: `cron.go`, `queue.go`, `router.go`, and `main.go`. `cron.go` schedules a task to run every minute. `queue.go` defines handlers for processing tasks from the queue, including email sending and report generation. `router.go` creates HTTP endpoints to enqueue these tasks using the Gin framework. `main.go` orchestrates the components, including a graceful shutdown mechanism. The application uses Redis as the backend for the task queue. Dependencies are managed with `go modules`. To run, build and execute the application, then test the endpoints to enqueue tasks and observe execution logs. A graceful shutdown is implemented to ensure clean termination. The tutorial concludes with instructions for testing the application.
