## What it is
Pebble is a LevelDB/RocksDB-inspired embedded key-value storage engine written in Go, using LSM-tree based block-based tables and RocksDB-compatible file formats. It is the default storage engine for CockroachDB and is production-ready at scale.

## Use cases
- embed a key-value store in a Go application
- replace RocksDB with a pure Go storage engine
- store data with an LSM-tree database
- build a distributed database needing a storage layer
- perform fast range scans and prefix iteration
- ingest SSTable files in bulk

## When to choose
- you need an embedded, pure-Go key-value store with no cgo dependencies
- you want RocksDB-compatible file formats with better Go concurrency
- you need fast reverse iteration and efficient compactions
- you're building a database or storage system in Go

## When to avoid
- you need RocksDB features like column families, transactions, or backups
- you want a client-server database rather than an embedded library
- you need to open existing RocksDB databases using unsupported features
- you're not working in Go

## Facets
- artifact type: library
- maturity: stable
- function: database, caching, serialization
- domain: databases, developer-tools, performance
- platform: go, windows, cross-platform
- tags: key-value-store, lsmtree, storage-engine, embedded-database, sstable, leveldb, rocksdb, linux, macos
