I wouldn’t call it gymnastics. The surprising part of the article was that Git itself is an object store that happens to use a filesystem for persistence, but an S3 bucket might actually be more suitable than a .git directory on POSIX.
replyIt makes sense, similar to how blob storage is a natural fit for a nix cache, where you have a giant flat space of many hash-address immutable directories/archives.
replyI think most of the pain documented in the article is just that git-the-implementation contains a lot of assumptions about it being a (local) filesystem that it is operating on, hence stuff like calling stat a ton of times, or doing the rename trick to get atomic behavior from a not-normally-atomic operation (updating a file in place).
If it were possible to define a "backing storage" API layer within git, it might be possible to move all the filesystem/posix-centric stuff to the other side of it and leave behind an interface that maps quite nicely to blob storage.

replyAuthor of the article here. I'm aware of ZeroFS and other similar approaches (such as something internal at Tigris that will become public at a later date), this was more of an experiment to see how far you can get with stuff I already had "on the shelf". I am going to be improving this a fair bit; I just need to plan out what I'm gonna work on and figure out the best times to stream it, etc.
replyWould probably be great to have ZeroFS backed PVs for the K8s folks :)
