S2
From Just Solve the File Format Problem
S2 by Klaus Post is an extension of Snappy for high throughput. It compresses single files or stream data and is used in the MinIO object store and the Kopia backup program
Compared to Snappy, it offers better compression, concurrent stream compression, skip forward in compressed stream, random seeking with indexes, less overhead on incompressible data, and more.
Decompresses Snappy data, but faster
Optionally creates Snappy-compatible data
