I have a cluster of 3 nodes and I've created a topic with some number of partitions and some number of replicas, let's say 10 and 2, respectively. Later, after I've got my 3 nodes fairly consumed with data in the 10 partitions, I want to add 2 more nodes to the mix to help balance out the partitions/replicas of my topic across 5 physical nodes instead of just 3.
I was assuming Kafka would just notice the new node and auto-replicate partitions to it but research is telling me that this probably isn't the case. Let's say I want no data loss and I want Kafka to spread my 10 partitions across all 5 nodes. How would I do this currently?
