BuntDB is an embeddable, in-memory key/value database written in Go, with optional persistence to disk. It is built for scenarios where you want a lightweight, fast store (reads and writes in memory) but also durability (via append-only file format) and transactional semantics (ACID with single-writer, multiple-reader locking). Among its distinguishing features are support for custom indexing (even within JSON values), spatial (geospatial) indexes with support up to 20 dimensions, flexible iteration over keys (ascending, descending, ranges), TTL/expiry eviction, and embeddability. Because it keeps its data in memory (with persistent backing), it's well suited for caching, session stores, small-scale databases inside Go applications, or applications that prefer simplicity and speed over massive scale. The API is simple, and the library is easy to embed into Go apps.

Features

  • In-memory key/value store with optional persistence
  • Embeddable with a minimal API
  • Custom indexes (including indexing fields inside JSON documents)
  • Geospatial indexing (multi-dimensional)
  • ACID transactions (many readers, one writer) with rollback support
  • TTL/expiry of items and flexible iteration (range, ascend, descend)
