Features

• Recurring Job Scheduling - Provides a system for executing recurring tasks on a fixed timetable using standard cron expressions.
• Cron Scheduling - Provides a mechanism to parse cron-style timing strings into executable scheduling rules.
• Background Task Runners - Automates repetitive background tasks and system maintenance work within a Go runtime.
• Task Schedulers - Provides a task scheduler for managing periodic job execution within the Go runtime.
• Calendar-Based Job Scheduling - Enables the definition of precise execution patterns for application logic triggered by the clock or calendar.
• Time-Based Triggers - Triggers task execution by polling the schedule at regular intervals to check for reached deadlines.
• Job Queues - Maintains a priority queue of pending tasks to efficiently trigger the job with the nearest deadline.
• Periodic Loop Executions - Schedules code to run repeatedly at fixed intervals for tasks like reports and data synchronization.
• Goroutine Scheduling Models - Implements a goroutine-based execution model to ensure that individual tasks do not block the main scheduler.
• Unified Task Interfaces - Uses a generic job interface to allow any custom Go logic to be wrapped as a schedulable task.
• Task Scheduling and Queues - Cron job library.
