High-performance Piecewise Geometric Model (PGM) learned index implementation in pure Rust with strict epsilon error guarantees
Save to My finds to follow releases and star growth. Saved in this browser.
About the project
A zero-dependency pure Rust implementation of a Piecewise Geometric Model (PGM) learned index: replaces B-Trees with a mathematical CDF approximation under strict epsilon error bounds, offering faster lookups and drastic memory savings over BTreeMap.
Useful for
- Replace BTreeMap in a sorted-key index with PGM to cut memory usage
- Speed up point lookups over timestamps or auto-increment keys
- Study the single-pass piecewise linear approximation algorithm

The star-growth assessment does not verify whether the project is safe to run.
Stars per day
Bars show stars per UTC day; the line is a moving average of available history. Gaps mean missing data, not zero growth. Today's bar is incomplete. Red marks spike days.
Why it’s trending
- Star-counter measurements on 2026-10-18 (UTC), 11:45–12:28: 104 → 109 stars (+5). This is the change over that interval.
- Estimated end-of-day forecast: about +18 stars, using observed gains and the previous day.
- The repository is 3 days old and already has 109 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Top new repositories this week: #186.

Star trust
Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.
These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
