About:
LZ4 is a lossless compression algorithm that is extremely fast, offering compression speeds up to multiple GB/s per core. It features an extremely fast decompressor, often exceeding RAM speeds in certain scenarios. This makes it ideal for performance-critical applications where data throughput is a priority.

Key Features:

Extremely fast compression and decompression speeds
High compression ratio comparable to zlib
Large block format (LZ4F) supporting dictionary compression
BSD 2-Clause License

Use Cases:

Real-time data logging and streaming
Database and file system compression
Network protocol optimization
Game engine asset loading

Alternatives:

zstd – Zstandard offers higher compression ratios at the cost of speed, whereas LZ4 prioritizes raw throughput.
gzip – Gzip is ubiquitous but significantly slower than LZ4 in both compression and decompression.
