Zstandard (zstd) 1.5.7
Zstandard is a fast compression algorithm providing high compression ratios. It offers a very wide range of compression/speed trade-offs, while being backed by a very fast decoder.
Features
- Real-time compression: Suitable for scenarios where compression speed is critical
- High compression ratios: Comparable to zlib with significantly faster compression
- Wide range of levels: From ultra-fast to maximum compression
- Small data optimization: Special mode for compressing small data chunks
- Dictionary compression: Enhanced compression for repetitive data patterns
- Streaming support: Compress and decompress data streams
Applications
Zstandard is designed for modern systems and is particularly well-suited for:
- Real-time backup systems
- Network data transfer
- File compression utilities
- Database compression
- Container image compression
Performance
Zstandard provides significantly better compression ratios than lz4 and much faster compression than zlib, making it an excellent general-purpose compression algorithm for a wide range of use cases.
Included Programs
- zstd: Main compression/decompression utility
- zstdcat: Decompress to stdout (link to zstd)
- zstdgrep: Run grep on compressed files
- zstdless: Run less on compressed files
- zstdmt: Multi-threaded version (link to zstd)
- unzstd: Decompression utility (link to zstd)
Library
The package includes the libzstd shared library, allowing other applications to use Zstandard compression capabilities.
