I worked at Meta and used Eden. I remember it as a virtual, FUSE based file system for a huge monorepo. Basically, if you have GBs of data in your monorepo, and any individual user accesses < 1% of it, then there's no point in having each "hg update" update the other 99%. But we were explicitly dissuaded from having binary data. I worked on image processing, and wanted to store test images for unit tests in hg, but the consensus was, that was a bad idea. So we stored them in a separate data store, and had a make rule to fetch them as part of the build.
