Why Does Dragonfly Require Only Half the Infrastructure of Redis?

Dragonfly is an in-memory data management solution that offers significant cost reduction compared to other cloud services like Redis or Valkey. Through its multi-threaded, shared-nothing architecture and efficient snapshotting mechanism, Dragonfly can fully utilize modern hardware capabilities and maintain stable memory usage during write loads. Additionally, the Dashtable data structure reduces memory overhead by up to 40% in certain cases, while B+ tree-based sorted sets offer improved performance and reduced memory usage compared to Redis's skiplist. The new SSD data tiering feature further enhances cost efficiency by offloading less frequently accessed data to lower-cost storage. Overall, Dragonfly provides a powerful, cost-effective alternative for managing large in-memory datasets across various environments.
