I do not know personally you but I noticed that you posted the link to the announcement. I am guessing you are passionate about the technology and innovation. Dragonfly is much more than the licensing choice we made. I wish HN discussions here were about how fibers work in Dragonfly and how SSD tiering is gonna be implemented and how we provide atomicity for lua scripts while running many of them in parallel etc. Btw, Dragonfly relies on an io-engine called helio (roughly equivalent to tokio) that has been developed by me and open sourced under Apache 2.0.
