This guidance does not apply any longer. The overhead per shard has been significantly reduced in recent versions and removed rule of thumb will be too pessimistic in many if not most cases and might be too optimistic in other specific ones. => Replace guidance with rule of thumb per field count on data nodes and rule of thumb by index count (which is far more relevant nowadays than shards) for master nodes. relates #77466 Co-authored-by: David Turner <david.turner@elastic.co> Co-authored-by: Henning Andersen <33268011+henningandersen@users.noreply.github.com>
