## What it is
BadgerDB is an embeddable, persistent, and fast key-value database written in pure Go, serving as the storage engine for Dgraph. It is designed as a performant Go-native alternative to RocksDB, optimized for SSDs and supporting concurrent ACID transactions with serializable snapshot isolation.

## Use cases
- embed a fast key-value store in a Go application
- replace RocksDB or LevelDB with a pure Go alternative
- store metadata or state for distributed systems
- build a local persistent cache with high write throughput
- persist large datasets on SSDs from a Go service
- need ACID transactions in an embedded database

## When to choose
- you are writing Go and want zero CGo dependencies
- you need an embedded KV store with ACID transactional guarantees
- your workload is write-heavy and runs on SSDs
- you want a proven store serving hundreds of terabytes in production

## When to avoid
- you need SQL queries or relational schemas
- you need a network-accessible client-server database
- your dataset must fit in memory and you prefer an in-memory store
- you need rich secondary indexes or document queries out of the box

## Facets
- artifact type: library
- maturity: stable
- function: database, caching, serialization
- domain: databases, developer-tools, backend
- platform: go, windows, cross-platform
- tags: key-value-store, embedded-database, lsmtree, pure-go, acid-transactions, ssd-optimized, linux, macos
