README
Magento 2.2 has issues with giant cron_schedule tables. The cron job running time will increase when the table gets bigger, causing heavy CPU usage.
Identifing the problem
In one of our stores the cron_schedule table exeeded 1.000.000 rows. To identify the problem run the following SQL query:
SELECT count(*) FROM `cron_schedule`
Solving the problem
Remove the old rows in cron schedule:
DELETE FROM cron_schedule WHERE scheduled_at < Date_sub(Now(), interval 24 hour);
This module will execute the cleanup query once a day.
Installation
composer require vendic/magento2-clean-cron-schedule
