KeyDB

A Multithreaded Fork of Redis.

Visit Website →

Overview

KeyDB is an open-source, high-performance database that started as a fork of Redis. It maintains full compatibility with the Redis API while introducing significant performance improvements, most notably multi-threading. This allows KeyDB to achieve much higher throughput on multi-core machines. It also includes features not found in open-source Redis, such as active replication and direct backup to AWS S3.

✨ Key Features

  • Full Redis compatibility
  • Multi-threaded architecture for higher throughput
  • Active Replication for multi-master setups
  • Flash storage support (DRAM + SSD)
  • Direct backup to AWS S3
  • Sub-millisecond latency

🎯 Key Differentiators

  • Multi-threading provides a significant performance boost over single-threaded Redis
  • Drop-in replacement for Redis, making migration easy
  • Advanced features like active replication in the open-source version

Unique Value: Delivers significantly higher performance than Redis on modern multi-core hardware with minimal code changes, reducing infrastructure costs and complexity.

🎯 Use Cases (5)

High-throughput caching Real-time bidding Session management at scale Messaging queues Any Redis use case requiring higher performance

✅ Best For

  • Replacing Redis clusters with fewer, more powerful KeyDB nodes
  • High-traffic web application caching

💡 Check With Vendor

Verify these considerations match your specific requirements:

  • Applications that are not bottlenecked by Redis's single-threaded performance

🏆 Alternatives

Redis DragonflyDB Memcached

Offers a direct performance upgrade over Redis without sacrificing compatibility. Unlike Memcached, it provides the full rich data structure support of Redis.
