## What it is
Speedb is a high-performance embedded key-value storage engine that is 100% RocksDB compatible and works as a drop-in replacement library. It is optimized for modern storage hardware and large-scale workloads, offering improved write performance, stabilized throughput, and reduced memory consumption.

## Use cases
- replace rocksdb with a faster drop-in key-value store
- handle massive random write workloads without stalling
- reduce memory usage in an embedded storage engine
- store large-scale key-value data on modern SSDs
- improve write throughput for kafka streams state stores
- embed a persistent key-value database in a C++ application

## When to choose
- you already use RocksDB and want better performance without code changes
- your workload suffers from write stalls or inconsistent latency
- you need an embedded, high-performance key-value store on modern hardware

## When to avoid
- you need a network-accessible database or SQL features
- you prefer a storage engine with a larger community and long-term roadmap like RocksDB
- your platform or language bindings are not supported by Speedb

## Facets
- artifact type: library
- maturity: maintenance
- function: database, caching
- domain: databases, developer-tools, performance
- platform: windows, cpp, cross-platform
- tags: key-value-store, storage-engine, rocksdb-compatible, embedded-database, lsmtree, linux, macos
