I still see things from 7 days ago at the top when I sort by “active” while other posts have much more activity and are newer. “hot” is the same thing with most posts from 5 days ago.
On https://lemmy.ml/ and https://lemmy.world/ it seems like sorting by “active” is working, there are posts from around 3h ago that have 100 upvotes so that I would consider “active”.
I think bug-wise that only affects
hot. But if I understand whatactivedoes, it’s posts with lots of recent comments. So ifhotis broken and leaving the same posts up, probably those posts are gonna affectactiveas well… so even ifactiveisn’t bugged, it ends up being very slow to change because people sorting by hot keep seeing and commenting on the same posts.I would assume if the scheduled task thread is dead it won’t run any of the scheduled tasks to update hot, active or anything else that needs to happen on a schedule.
I believe hot is the only ranking that runs as a scheduled task, as it is uniquely expensive to compute. I believe others are updated in real-time. It’s possible I’m mistaken, but I’ve been watching a few GitHub issues and this is the impression I got from dev discussion there.
