## What it is
A minimal, extremely fast B+ tree indexing structure written in C, designed for billions of key-value storage entries on POSIX systems. It serves as both a practical on-disk index implementation and a learning resource, with an in-memory branch for debugging.

## Use cases
- implement a B+ tree index for key-value storage
- learn how B+ tree data structures work
- store billions of key-value pairs efficiently
- build a custom storage engine index
- debug B+ tree behavior with an in-memory variant

## When to choose
- you need a lightweight, dependency-free B+ tree implementation in C
- you want to understand or study B+ tree internals
- you need an on-disk index for very large key-value datasets on POSIX systems

## When to avoid
- you need a full-featured production database with transactions and replication
- you prefer a high-level language binding or managed storage solution
- you need Windows support without POSIX compatibility

## Facets
- artifact type: library
- maturity: maintenance
- function: database, file-system, search-engine
- domain: databases, developer-tools
- platform: c, cross-platform
- tags: bplustree, key-value-storage, data-structure, posix, indexing, algorithms, linux
