Dragonfly expects you to have the latest hardware[6] and the latest kernel[7] on all your servers. I find this outrageous because not all servers run 5.10 and a majority of them are still using long-running branches on 4.x.
I don't see anything wrong with that. Either your kv store is performing OK or can be scaled using the usual methods and it's not holding you back... or you actually critically depend on the fastest kv performance you can get. In the second case, you'll be likely happy to dedicate some time to standing up a couple of machines with updated kernels.

As far as I can tell, "latest kernel" really means "has io_uring"...which is core to how Dragonfly works, so it seems reasonable to me.
