krestenkrab/hanoidb

HanoiDB is an indexed, key/value storage engine built on a log-structured merge tree (LSM-BTree) architecture. It provides core data persistence capabilities including insert, delete, and read operations with O(log N) latency, alongside features like data expiration and on-disk compression. The system is designed for concurrent access and includes tools for benchmarking and visualizing internal state.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 68333fa51a — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
