 OnPair is a dictionary-based string compression algorithm designed for in-memory database workloads that need both strong compression ratios and fast random access to individual values. It builds its dictionary in a single sequential pass by incrementally merging frequent adjacent substrings, achieving compression comparable to BPE while being substantially faster and more memory-efficient. This crate is a Rust port targeted at the SpiralDB engine.
