Is there a recommended ZooKeeper topology for production Solr environments?
I was planning: 3 ZK nodes, each on its own dedicated machine. Thinking that dedicated machines, separate from Solr servers, would keep ZK isolated from resource contention spikes that may occur on Solr. Also, if a Solr machine goes down, there would still be 3 ZK nodes to handle the event properly. If I want to save on resources, placing each ZK instance on the same box as Solr instance in considered common practice in production environments? Thanks!
