Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder (see benchmarks below). It also offers a special mode for small data, called dictionary compression, and can create dictionaries from any sample set. Zstandard library is provided as open source software using a BSD license.
From the same developer of the LZ4 compression format and tool. This patch is for the Zstandard shared libraries and compression tool.
