Here is a Go implementation of FSST, a fast static symbol table compression. It comes with training, encode/decode helpers, and examples. It’s great for logs and JSON data.

Reference implementation: https://github.com/cwida/fsst Paper: https://www.vldb.org/pvldb/vol13/p2649-boncz.pdf

Benchmarks and tests are in the repo - feedback welcome.
