No disclosure of inspiration from Manta https://github.com/joyent/manta?

Also, why yet another DFS that makes excuses for shitty local filesystems instead of leveraging ZFS? Use ZFS as the base for integrity, snapshots, send/receive and make a small service on top for managing cluster metadata.




Hi, JD @ Pachyderm here.

We think Manta is pretty cool but it wasn't actually an inspiration for us.

I'm not sure I fully understand your criticism of the filesystem. Pfs was actually initially conceived as almost exactly what you're describing, a small service on top of ZFS. But we realized early on that ZFS was going to be a pain because of its patent status so we used btrfs instead. I think btrfs is worse than ZFS but I'm not sure I'd call it a shitty local filesystem.
