About dragonfly
Dragonfly is an in-memory data store designed as a modern replacement for Redis and Memcached. It is fully compatible with both Redis and Memcached APIs, allowing adoption without code changes. The software is optimized for modern application workloads, offering higher throughput and better resource efficiency compared to traditional solutions.
Benchmarks indicate Dragonfly achieves significantly higher throughput than Redis while maintaining comparable latency. It scales vertically with instance size, unlike single-threaded alternatives. The system also demonstrates improved memory efficiency during operations like snapshotting.
