## What it is
Tendis is a high-performance distributed key-value storage system fully compatible with the Redis protocol, built on RocksDB for disk-based persistent storage. It uses a decentralized gossip-based cluster design similar to Redis Cluster, supporting horizontal scaling, online data migration, and automatic failover.

## Use cases
- store redis datasets larger than memory on disk
- run a redis-compatible database with persistent storage
- scale a redis-like kv store to hundreds of nodes
- reduce storage costs for redis workloads with cold data
- self-host a distributed redis alternative

## When to choose
- your dataset exceeds available memory and redis costs are too high
- you need redis protocol compatibility with PB-scale disk-backed capacity
- you want a decentralized cluster with automatic failover like redis cluster

## When to avoid
- you need the absolute lowest latency of in-memory redis
- you rely on redis commands or features Tendis does not implement
- you need a cross-platform solution - only Linux x64 is supported

## Facets
- artifact type: service
- maturity: active
- function: database, caching, search-engine
- domain: databases, big-data, backend, microservices
- platform: cpp, self-hosted
- tags: redis-compatible, rocksdb, kv-store, nosql, distributed-cluster, persistent-storage, linux
