Thanks for the article! We have a tiny hosted ELK cluster for our app logging, but we don't have much expertise in good cluster design. We recently implemented monthly rolling indices, and currently have a single 'archive' index for the old data (from the past two years) sharded into 25GB chunks. Would it make sense from a query performance perspective to add extra replicas to the 'archive' shards, to help spread the load between the nodes? Thanks for any thoughts!
