As was said it depends on what tradeoffs you want between availability and data loss risk.
If you're most concerned about the data then I recommend having it replicated to at least 3 brokers, set minimum ISR to 2 and produce to the topic with acks = -1. Also set "unclean.leader.election.enable" to false on the broker config. I've been using that setup without data loss for a while now.
