We can't ignore or pretend that network partitioning doesn't happen. When people talk about choosing two out of CAP the real question is C or A because P is out of our control.

When we combine network partitioning with single local data suffix loss it either leads to a consistency violation or to a system being unavailable desperate the majority of the nodes being are up. At the moment Kafka chooses availability over consistency.

Also I read Kafka source and the role of network partitioning doesn't seem to be crucial. I suspect that it's also possible to cause similar problem with a single node power-outage https://twitter.com/rystsov/status/1641166637356417027 and unfortunate timing
