KeyDB is a multithreaded, high-performance fork of Redis that is fully protocol-compatible and acts as a drop-in replacement for Redis deployments. It adds features like Active Replication, FLASH storage backed by RocksDB, subkey expires, and MVCC for non-blocking queries while achieving higher throughput on the same hardware.

Use cases

• replace redis with a faster drop-in alternative
• run a multithreaded in-memory key-value store
• scale redis workloads without sharding
• set up active-active replication for a redis-compatible cache
• store more data than fits in RAM with flash storage
• run a high-throughput cache over a million ops per second
• migrate an existing redis deployment with no client changes

When to choose

• you need higher per-node throughput than Redis on the same hardware
• you want a Redis-compatible database with built-in active replication and multi-master writes
• your dataset exceeds RAM and you want FLASH-backed storage
• you want KEYS/SCAN queries that don't block the database thanks to MVCC

When to avoid

• you need the newest Redis features or commands, since KeyDB development has slowed
• you rely on a large ecosystem of Redis modules or vendor-managed Redis services
• you prefer a single-threaded model with simpler operational reasoning
• you need long-term commercial support, which is not offered
