I like Dragonfly's ability to use all the computing resources of the machine it's running on. Customer support is also very good.

We saw a 30x speed up compared to managed redis and a 10x reduction in cost. Only took us about a day to integrate. No brainer for anyone currently using redis. The founding team is incredibly sharp and super responsive

I'm impressed by Dragonfly DB because it is easy to use with full compatibility with Redis APIs. Some design decisions, like multi-threaded architecture and focus on asynchronous operations, make it suitable for distributed systems in the modern cloud-native era.
