# About

Fastmash was created by **[Peder Bergan](https://pederbe.dev)**, who designs,
builds and maintains it.

The project started from a practical question: can a tool people use every day
in data pipelines be made substantially faster, without asking them to change
their commands, and without giving up correctness? Fastmash answers it with
careful engineering: a Rust implementation of the whole GNU datamash command
language, arithmetic that gives identical results on every machine, and
performance claims backed by published measurements.
