Description
⚠️ This issue respects the following points: ⚠️
- This is a bug, not a question or a configuration/webserver/proxy issue.
- This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
- Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
- I agree to follow Nextcloud's Code of Conduct.
Bug description
The query 4f0fc707a2e82ec699067a969cd17b05
SELECT
*
FROM
`oc_jobs`
WHERE
(`reserved_at` <= ?)
AND (`last_checked` <= ?)
AND (`time_sensitive` = ?)
ORDER BY
`last_checked` ASC
LIMIT
?does not use a covering index. The index job_lastcheck_reserved only covers last_checked and reserved_at, not time_sensitive. The database has to scan a bunch of rows every time cron picks the next job outside the maintenance window:
Steps to reproduce
- Install Nextcloud
- Configure a maintenance window
Expected behavior
An index on (last_checked, reserved_at, time_sensitive)
