JuiceFS
JuicedataJuiceFS is a POSIX-compatible distributed file system that stores file data in object storage such as Amazon S3 while keeping metadata in a separate database engine - Redis, MySQL or TiKV among them. Training and analytics jobs mount it and read cloud storage as files without code changes. Juicedata develops it.

Adoption
3 low confidence14,334 GitHub stars, which lands in the >10K stars band of the stars scale, level 3. The `juicefs` package on PyPI is a third-party Python SDK published from another organization's repository and drawing under 200 downloads a month; it is not this product's distribution channel, which is a Go binary and a CSI driver. The stars scale therefore applies, capped at 3.
