Maybe I'm completely misremembering things, but at some point wasn't there a hotfix to Lemmy that hard-limited how many comments a thread could have? Does anyone know if there's a maximum and if so how many?
Just wondering, cause uh, I could see this one having a lot of comments.
The fix you are referring to only limits how many comments can be retrieved in a single API call (300). This limit is only used when specific parameters are passed, not in all cases.
Tree-paging is a pretty complicated issue, and we really do need some DB / SQL experts to help us with figuring out how to page them correctly. The limit is 300, but only for the top-level comment fetch, which could also have different slices whether you sort by top, or new, and doesn't apply to the nested comments, which could have thousands.
The limit is a kludge, because ppl were creating thousands of comments, and without proper paging, it was affecting performance.
