Dragonfly
Dragonfly is an in-memory data store for real-time workloads such as caching, feature serving, message queues, and sorted-set leaderboards.
What Dragonfly is
Dragonfly is an in-memory data store for real-time workloads such as caching, feature serving, message queues, and sorted-set leaderboards. It supports strings, hashes, lists, sets, sorted sets, streams, JSON, vectors, geospatial data, and probabilistic structures. Redis and Memcached API compatibility is intended to avoid code changes. Its multi-threaded, shared-nothing architecture uses CPU cores and automatically shards data between them. The maker states performance of millions of queries per second per instance with sub-1ms P99 latency, and describes 30–60% better memory utilization from data structures and compression. Data persistence, high availability, and vector search are supported; SQL is not. Dragonfly runs in Docker and as a single binary through Docker, Kubernetes, or other environments. Cloud deployments support AWS, GCP, Azure, on-premises, and bring-your-own-cloud.
Good
- Redis and Memcached API compatibility
- Automatic sharding across CPU cores
- Supports persistence, high availability, and vectors
- Docker, Kubernetes, cloud, and on-premises deployment
- Prometheus and S3-compatible snapshot support
Watch out
- No SQL support
- Self-managed pricing requires contacting the company
- Cloud security controls are listed for Dragonfly Cloud
Who it suits
Dragonfly suits teams building real-time caches, feature stores, queues, or leaderboard systems. It fits users needing Redis or Memcached API compatibility and self-managed or cloud deployment options.
Verdict
Dragonfly combines broad data-model support with Redis and Memcached compatibility and automatic sharding. Consider its lack of SQL and the separate pricing and control differences between cloud and self-managed options.
