Giteabot c3b7120042 Add index to `issue_user.issue_id` (#27154) (#27158) ... Backport #27154 by @JakobDev This fixes a performance bottleneck. It was discovered by Codeberg. Every where query on that table (which has grown big over time) uses this column, but there is no index on it. See this part of the log which was posted on Matrix: ``` 2023/09/10 00:52:01 ...rs/web/repo/issue.go:1446:ViewIssue() [W] [Slow SQL Query] UPDATE `issue_user` SET is_read=? WHERE uid=? AND issue_id=?
