I quickly went through the docs but didn't see a reference to be able to dynamically schedule and unschedule tasks at runtime. I've used APScheduler in the past and it does support this.

The use case is wanting to have let's say a web form where a user can say they want to run a task at XYZ interval and then they can schedule and unschedule it on demand. APScheduler will pick these up without needing to restart anything.

Does your library support that? If not, is that a planned feature?

Do you mean with "dynamically schedule and unschedule" that you sort of manually (or using another task) stop running a task in its specified interval (or condition)? It does support this, there is an argument "disabled" in the tasks that can be set True and then the task won't be run unless explicitly forced to run (calling run method of a task). The task can be enabled by setting it back to False. This can be done in runtime in another task using main, thread or async execution.

It could be the docs don't mention this. I'll need to check and add it there in case it's missing.

Or did I misunderstand?

Dynamic as in you don't need to predefine the task in a config file or decorator before you start your server.

This way you can load and unload tasks at runtime based on user input which you can optionally and independently save in your own database.

Like imagine a user wanting to control when a backup happens. You can ask them to fill out a form on your site to say "ok run this every day at 4am" and that would spawn a new job that executes at that interval and the user can also delete that and the job would be removed. There might be 100 different users each with their own individual backup jobs that are running or not running.

Sorry, I'm in quite a hurry (so sorry for the language and lack of ellaboration).

You can create tasks dynamically and you can create them after starting the scheduler. You can use app.session.create_task and pass "func" (Python function) for it or path and func_name if you wish to lazily load the task function (imported only when executing the task). You can also pass a command for this method as well.

And you can create a task that runs on startup (on_startup=True) and create your other tasks using this task. Use main, async or thread as execution. Then you can create other metatasks that create/modify/delete the tasks on runtime with any logic you want. For example, sync them with a database.

I'm planning on doing a proper demo about this at some point.
