Mergent offers two main constructs to manage your background jobs: tasks and schedules. Although they are used to accomplish similar goals, their usage and functionality are quite different.

Tasks

Think of a task as a single unit of work. You can create tasks when certain events occur in your application - a user making a purchase, signing up for your newsletter, and so on. Once such a task is created, Mergent adds it to a queue and ensures it’s reliably processed by your application. Tasks are ideal for one-off, asynchronous jobs that need to be done outside the main application flow.

​
Schedules

Schedules represent recurring work that needs to be done at regular intervals. These intervals can be defined by a cron expression or an rrule, giving you the flexibility to schedule tasks as often as needed - be it every minute, daily, or even every third Tuesday of the month. When a schedule is triggered, it creates a task, just like any other task you’d manually create. Mergent then sends this task to your application for processing. Schedules are perfect for tasks that occur regularly, like sending out weekly newsletters, generating monthly reports, or performing daily data clean-up.
