What is a feasibility to implement IPFS for lemmys image hosting?
We have a bunch of instances hosting basically the same images multiple times. Using IPFS we could increase the availability of images for users with almost no cost to instances. I have heard rumors that pict-rs can't be easily scaled up due file system based storage and would need a rewrite.
I think Fediverse is major thing where using IPFS on the decentralized network makes sense.
The images that don't originate on your instance are only temporarily cached. Pict-rs can use object storage which provides virtually unlimited space and is cheaper.
How long are they cached for? I still have cached images from over 2 months ago.
