Simple to scale

Dragonfly takes advantage of every core, memory and network byte to scale vertically with your instance resources. It grows with you from the first bytes to hundreds of gigabytes of in-memory datastore on the single instance.

Do more for less

Designed from the ground up in C++ to extract the most value from your infrastructure. Dragonfly takes advantage of every core, memory and network byte to scale vertically with your instance resources.

Built for performance

Dragonfly is a new in-memory engine, optimized for throughput, using a thread-per-core architecture without locks to deliver stable and low latencies. Using true async interfaces, Dragonfly takes advantage of all hardware resources to their limit.
