## What it is
NutsDB is a simple, fast, embeddable and persistent key/value store written in pure Go. It supports fully serializable transactions and data structures such as lists, sets, and sorted sets.

## Use cases
- embed a persistent key-value store in a Go application
- store lists, sets, and sorted sets locally without a database server
- need ACID serializable transactions in an embedded store
- replace BoltDB/BadgerDB with a fast pure-Go KV store
- persist small-to-medium datasets with low latency
- build local caching or metadata storage in Go

## When to choose
- you want an embedded, serverless key-value database in pure Go
- you need transactional reads and writes with rich data structures
- your dataset fits on local disk and you want simple deployment

## When to avoid
- you need a network-accessible, multi-client database server
- you require SQL or relational queries
- you need very large datasets beyond local disk capacity

## Facets
- artifact type: library
- maturity: active
- function: database, serialization, concurrency
- domain: databases, developer-tools, backend
- platform: go, cross-platform
- tags: key-value-store, embedded-database, bitcask-style, transactions, data-structures, pure-go
