I wish zstd supported seeking and partial decompression (https://github.com/facebook/zstd/issues/395#issuecomment-535...). We could then use it for hosting disk images as it would be a lot faster than xz which we currently use.

Fun fact: Two zstd files appended is a zstd file.

Also, parallel zstd must have some way to split up the work, that you could maybe use too.

I would suggest reading the github issue that I linked to, you'll see why it's not currently possible.
