설명
Action Scheduler is a scalable, traceable job queue for background processing large sets of actions in WordPress. It’s specially designed to be distributed in WordPress plugins.
Action Scheduler works by triggering an action hook to run at some time in the future. Each hook can be scheduled with unique data, to allow callbacks to perform operations on that data. The hook can also be scheduled to run on one or more occassions.
Think of it like an extension to do_action() which adds the ability to delay and repeat a hook.
Battle-Tested Background Processing
Every month, Action Scheduler processes millions of payments for Subscriptions, webhooks for WooCommerce, as well as emails and other events for a range of other plugins.
It’s been seen on live sites processing queues in excess of 50,000 jobs and doing resource intensive operations, like processing payments and creating orders, at a sustained rate of over 10,000 / hour without negatively impacting normal site operations.
This is all on infrastructure and WordPress sites outside the control of the plugin author.
If your plugin needs background processing, especially of large sets of tasks, Action Scheduler can help.

Developers refuse to support their own plugin. I have no use for something that does not work, and something the developers will not support.
Cannot and will not recommend to anyone... sadly will not make much of a difference because it's in use in every site that utilizes WooCommerce, but, whatever...

Look, I'm fine with having to do some coding. After all, I want to write my own php code to be called every five minutes or so. But you have to tell me WHERE to put the calls. I've installed your service via plugin, and your usage page (actionscheduler [dot] org [slash] usage) tells me exactly nothing about where I need to make these API calls. Is it function.php in my home WP directory? Can I make these calls from my own self-made directory? Tell me!

I had migrated a ton of sites to a new server and (I thought) tested them. But one site malfunctioned when I tested it again and woocommerce would not activate without fatal errors.
The error involved the action scheduler Fatal error: Uncaught Error: Class 'Action_Scheduler\Migration\Controller' not found in
I had already paid a ton of money to migrate the site from another ecommerce system to woocommerce b efore this latest server change so this was a nightmare.
Your plugin fixed it and saved me much heartache. Sincere thanks.

How Action Scheduler only has two reviews is beyond me, though I guess I more typically use it as a library within whatever I'm developing rather than as an actual plugin.
Regardless, Action Scheduler is awesome and an absolutely vital contribution to the WordPress community. It's really the only good way to reliably get intensive, bulk recurring actions happening with useful reporting on if scheduled events are happening and such. WAY better than trying to leverage WP's native "wp-cron" task scheduling system.
Documentation is good too. What more could you ask?

I'm not sure why this plugin hasn't been downloaded more often or hasn't got more positive reviews. It's really helpful for scheduling long running tasks and the logging functionality for viewing and debugging issues is excellent. I wish I had known about it sooner.
