Redis, a popular in-memory data store, has faced limitations due to its single-threaded architecture and snapshotting algorithm, affecting performance and scalability. Additionally, recent licensing changes have caused concerns within the developer community. Dragonfly emerges as an alternative with modern data structures and a multi-threaded shared-nothing architecture, offering 25x the performance of Redis at up to 80% lower infrastructure costs. Furthermore, its permissive licensing approach ensures stability and transparency for developers.
