Faster storage means faster messages. 🔥**High Availability** Through a modified raft distributed protocol, automatic disaster recovery is achieved. If one machine fails, another machine automatically takes over without external perception. Decentralized, no single point, no central node, each node is independent and equal, all can provide services. Easy expansion, just add machines, no need to shut down, no need to migrate data, automatic data allocation according to strategy. 0⃣️ **Ease of Use** Does not rely on any third-party middleware, simple deployment, can be started with one command. Adopts the design concept of channel subscription and publishing, easy to understand, easy to use. As simple as Redis, as high-performance as Kafka, as reliable as MySQL. 🌲**Technical Support** Official team provides technical support, technical documentation, technical exchange group, and issue feedback.
