I'd like to learn more about JuiceFS, but from their architecture diagrams I'm struggling to see what benefit they provide if they're a layer over blob store systems like Ceph, MinIO, etc.
It looks as though you need to set up the underlying storage engine that has its own recordkeeping (one point of failure), then layer JuiceFS on top — another point of failure, and I don't know what it gives you.
It's good that it's fast, but if it's pointing to another blob store you'd... expect it to be fast? Is this only needed if you want properly faked file system primitives over blob stores, if you can't use blob stores directly? Definitely need to spend some time reading.
