If anyone knows a similar solution for zstd, I'm very interested. I'm doing streaming uncompression to disk and I'd like to be able to do resumable downloads without _also_ storing the compressed file.
Note, however, that this can only seek to frames, and zstd still only creates files containing a single frame by default. pzstd did create multi-frame files, but it is not being developed anymore. Other alternatives for creating seekable zstd files are: zeekstd, t2sz, and zstd-seekable-format-go.
Thanks, this is helpful. I might just end up using content defined chunking in addition/instead, but it's good to know that there is a path forward if I stick with the current architecture.
