[Feature Request]: Allowing chunks to save when leaving and rejoining a server.

[f-loading]

Me and my friend primarily use this mod for keeping the server ram lower but it's annoying having to re-explore the chunks to be able to see them from far away again, is there a chance that we could be able to save chunks on a server after relogging? I noticed there's a mod called bobby that does this, but it crashes me so my only option is this.

I would also be happy to have this function too.

there is pros and cons to that functionality, it adds a decent bunch of complexity overhead and does also use more resources on your machine(cpu core for loading/saving things to disk, disk space). And the added complexity also introduces more bugs, as you can see with bobby

Plus here. You do not need very intensive disk IO. Save periodically only in a separate low-priority thread. Reload slowly, not all at once etc. Distant Horizons mod does it, but, unfortunately, it is not supporting well Embeddium/Oculus and the decreasing of the render quality of far land drawing is too bad.

Sorry to bring this up, but, yes, that would be a good addition, it can be made as a toggle, so that a player would chose what mode he wants to use (or just a different fork of the project). Not to mention, that 1.12.2 misses that kind of mod (i mean, it is old, but a lot of modpacks are still made to this version. Also, recently, the 1.12.2 fork of this mod was updated, so i still hold hope for further development). There is a FarPlaneTwo, but it is very raw and works by an absolutely different principle.
P.s. i can understand if the feature won't ever be implemented, but we'd really like to see it
Upd: Just noticed it's a duplicate of #26, but still, i should give it a try, maybe you changed your mind

I was looking for this exact function, it is one of the last ones that is not available.

@someaddons Would it be possible to make this feature optional through configuration settings? For example, having a persist_stored_chunks option to enable or disable cached chunk saving, along with a persist_chunk_size to define the maximum file size. When the limit is reached, older chunks could be overwritten so only the most recently visited chunks remain. The server could refresh any saved chunks with updated content, ensuring they stay current while still offering users a choice in how much data is preserved.

This way, the added complexity can be disabled by default, and a clear warning can be included on the description and on the config to tell users about any potential performance impact.

Love this mod btw, and also appreciate all of your other performance mods (I use all of them)!

bringing life to this again.
I also think this should be added because i like to see far but for me personally using farsight is not worth it if every time i am inconvenienced by having to yet again reload chunks.
now i have a beefy PC my self, so it asking a bit more from my machine is fine if i can just unburden my server a bit then for far distance views.
But ye it should be a toggle option for those that do not have beefy PC's.

Exactly! Right now, it's a useless mod, just about completely! It's not BOBBY at all. Why even bother making it?
