I am the author of https://pypi.org/project/cython-zstd/ and I advise Debian to rather package it.
https://pypi.org/project/zstd/ issues: - written in pure C: writing bindings without Cython is really looking for bugs - it fails to compress b'' Other advantage of https://pypi.org/project/cython-zstd/: - as an optimization, compress() resizes the output buffer rather than doing a copy or waste memory ('zstd' egg does the latter) Unfortunately, for the only place where I planned to use zstd in a Python program, gzip remains better ( https://github.com/facebook/zstd/issues/1134 ). So I didn't follow recent changes in zstd API and I see that https://pypi.org/project/zstd/'s compress gained a 'threads' parameter (which https://pypi.org/project/cython-zstd/ does not have). On https://lab.nexedi.com/nexedi/cython-zstd you'd find 2 branches: - debian, where I started Debian packaging - stream, for the stream API: I don't remember if it's working Julien
