Ardb is a Redis-protocol-compatible persistent NoSQL key-value server written in C++ that supports pluggable storage engines such as RocksDB, LevelDB, LMDB, WiredTiger, PerconaFT, and ForestDB. It supports most Redis commands, data structures, replication, Lua scripting, pub/sub, transactions, and works with existing Redis clients.

Use cases

• run a redis-compatible server with disk persistence
• swap storage engines like rocksdb or lmdb under a redis protocol server
• use redis clients against a persistent key-value store
• replicate redis data to a persistent nosql slave
• store redis data structures like sorted sets and hashes on disk
• self-host a redis alternative with online backup

When to choose

• you need Redis semantics but data must persist durably to disk
• you want to choose a specific LSM or B-tree storage engine backend
• you want to use existing Redis clients and tooling unchanged
• you need Redis replication or sentinel failover with persistent storage

When to avoid

• you need the full latest Redis feature set or newest commands
• you only need an in-memory cache and can just use Redis
• you need a very actively maintained project - the latest release is from 2021
• you need cluster/sharding features beyond what Ardb supports
