Where does Lemmy store upvotes, downvotes, and replies? (lemmy.world)

Does ActivityPub send those to other instances, or does ActivityPub only send the original post and the rest (upvotes, downvotes, replies) are stored only on the original server where the post was made?

I'm a bad example. I haven't properly tuned the settings, currently RAM will grow to whatever is available.

I'm very lucky, the instance is running in a proxmox container alongside some other fediverse servers (run by others), on dedicated hardware in a datacentre. The sysadmin has basically thrown me plenty of spare resources since the other containers aren't using them and RAM not used is wasted, so I've got 32GB allocated currently. I still need to restart once a week or that RAM gets used up and the database container crashes.

It's been on my list of things to do for a while, try some different postgres configs, but I just haven't got around to it.

I know a couple of months back lemmy.world were restarting every 30 mins so they didn't use up all the RAM and crash. I presume some time and some lemmy updates later that's no longer the case.

I know some smaller servers get away with 2gb of RAM, and we should be able to use a lot less than 32GB if I actually try to tune the postgres config.
