Hi there - I see you're Mr Kafka :-) I wanted to use Kafka instead of Raft for my project, but for my application I couldn't tolerate the (even highly unlikely) possibility of losing a message (when we lose all the nodes in the In-Sync Replica set). I understand why this tradeoff is there (for the clickstream use-case), but I hope it might be possible to retrofit reliable writes to support other use cases as well. The more open-source reliable log services we have the better!
