My lemmy instance seems to be using a lot of storage, I am the only one using it and for like 10 minutes a day. it's currently using about 122 gb, after about 3 months of usage

 ~/l/volumes> sudo du -d 1 -h  .
47G	./pictrs
75G	./postgres
0	./lemmy-ui
122G	.

seeing the usage of other ppl this seems really big? Am i doing someting wrong? edit: it is also using a lot of memory, i dont know exactly how much but it seems to be most of my system's available ram (16 gb)

I don't remember which update it was but newer versions of Lemmy use significantly less database storage.

It reduced it shortly, but the activity table is still (unecessarily) caching most of the lemmyverse for 3 months AFAIK.

Our database went from 30GB or so down to 7GB with that update, but now it is back to 30GB or so. I even did a full database vaccuum lately, but it only shaved off 2-3GB or so.

If my understanding is correct, then the activity table probably doesn't need to store more than a week or so, instead of the current 3 months. But this is something hard-coded in Lemmy and can't be easily configured.
