AI-generated summary

LZ4 is a lossless compression algorithm renowned for its exceptional speed, offering compression speeds exceeding 500 MB/s per core and decompression speeds in the multiple GB/s range. It provides flexibility through an acceleration factor to tune compression ratio versus speed and includes a high-compression derivative, LZ4_HC. The algorithm is also compatible with dictionary compression, enhancing performance on small files when used with tools like Zstandard's Dictionary Builder.
