in-memory data store / Redis-compatible cache
Dragonfly is an in-memory data store compatible with Redis and Memcached, designed for high throughput and low latency.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.
Redis-compatible remote cache-store with high performance; choose if you prefer a C# implementation and need a drop-in Redis replacement
Garnet is a remote cache-store from Microsoft Research that offers strong performance (throughput and latency), scalability, storage, recovery, cluster sharding, key migration, and replication features. Garnet can work with existing Redis clients.
community-driven Redis fork, drop-in replacement; choose for Redis compatibility with active development
A flexible distributed key-value database that is optimized for caching and other realtime workloads.
Redis-compatible database, active; choose if you want a similar drop-in replacement from Qihoo
Pikiwidb is a Redis-Compatible database developed by Qihoo's infrastructure team.
An earlier or more limited way to do the job. Still the right call when you need something small, proven, or CPU-only.
multithreaded Redis fork that inspired Dragonfly, but stale; use if you need a feature set similar to Dragonfly and don't mind unmaintained code
A Multithreaded Fork of Redis
These projects were analysed and named dragonfly among their alternatives. The relationship is not symmetric — how dragonfly rates them is a separate judgement, made when dragonfly is analysed in its own right.
calls dragonfly “Choose when you need higher multi-threaded throughput while keeping the Redis protocol.”
For developers, who are building real-time data-driven applications, Redis is the preferred, fastest, and most feature-rich cache, data structure server, and document and vector query engine.
calls dragonfly “Redis-compatible server built from scratch for high throughput and memory efficiency, choose when you want a modern C++ implementation independent of Redis fork tree.”
A Multithreaded Fork of Redis
calls dragonfly “choose for a C++-based Redis/Memcached-compatible server with high throughput and lower memory when you don't need .NET”
Garnet is a remote cache-store from Microsoft Research that offers strong performance (throughput and latency), scalability, storage, recovery, cluster sharding, key migration, and replication features. Garnet can work with existing Redis clients.
calls dragonfly “choose when you need higher throughput on many cores via a multi-threaded shared-nothing architecture that replaces Redis and Memcached.”
A flexible distributed key-value database that is optimized for caching and other realtime workloads.
calls dragonfly “Choose it when you want an in-memory, multi-core-optimized Redis/Memcached-compatible server and can keep data in RAM.”
SSDB - A fast NoSQL database, an alternative to Redis
calls dragonfly “choose when Redis/Memcached-protocol high-throughput caching is all you need and you do not need Hazelcast's JVM data grid or stream processing.”
Hazelcast is a unified real-time data platform combining stream processing with a fast data store, allowing customers to act instantly on data-in-motion for real-time insights.
