## What it is
SummitDB is an in-memory NoSQL key/value database written in Go that persists to disk, provides ACID transactions, and replicates via the Raft consensus algorithm. It exposes a Redis-compatible API and supports custom indexes, JSON documents, geospatial indexing, and JavaScript scripting.

## Use cases
- run a strongly consistent in-memory key-value store with disk persistence
- set up a highly available replicated database using Raft consensus
- use Redis commands with ACID transactions and strong consistency
- store and index JSON documents
- query geospatial data with spatial indexes
- run a lightweight NoSQL database on a Raspberry Pi or ARM device

## When to choose
- you need Redis-like simplicity but with strong consistency and durability instead of eventual persistence
- you want a small, easy-to-deploy replicated database with ACID guarantees
- you need ordered keys, value indexing, or spatial indexing in a key/value store

## When to avoid
- you need a battle-tested database with active development and a large community
- your dataset exceeds available memory since data is primarily in-memory
- you need a permissively licensed dependency (license is non-standard)
- you need rich query languages like SQL or full secondary-index ecosystems
