An open-source Python key-value store built around TTLs, reactive subscriptions, optimistic concurrency, and lock-free reads.

Landing page captured for the 2026-09-04 issue.

Field notes

NimbusKV presents an in-memory Python store whose state is represented as an immutable persistent HAMT snapshot; writers build and swap snapshots while retrying on conflict. Its API includes TTL expiry events, subscribe() callbacks, wait_for() conditions, and atomic() updates, with write-through options for SQLite, Redis, MySQL, and PostgreSQL. The homepage identifies version 3.0.1, links to PyPI and GitHub, and says the project was previously known as LiveDict.
