Zstandard

Use Zstandard Compression with Python compression.zstd

Python applications have long had standard-library support for gzip, bzip2, LZMA, and zlib. Python 3.14 adds another important option: Zstandard support through compression.zstd. Zstandard is useful when a system needs a practical balance of compression ratio and throughput. The new module means many applications can read and write .zst data without adding a third-party Python package. But choosing a compression API is not only about calling compress() and decompress(). Production code also needs to think about streaming, memory limits, frame boundaries, dictionaries, compatibility, and untrusted input.
