LZ4 compression library explodes with 300 new stars

Coding

What is lz4?

LZ4 is an open-source lossless compression library that can compress data at over 500 MB/s per CPU core and decompress at several GB/s. It offers a tunable acceleration factor for speed versus size and a high-compression mode called LZ4_HC.

Who it is for

Any developer building low-latency pipelines, caches, or storage can drop LZ4 in to move data faster without slowing down reads.
