Hi. I setup my cluster with only i3.2xlarge nodes and considering change to hot warm architecture.
With all of i3.2xlarge nodes, I don't have big issue to search documents.
But I'm worring about d2 type instance's search performance because it has spinning disk.
Does search performance of d2 type instance same with i3 type instance if d2 type instances aren't indexing?
For example about indices, there are daily 150M documents, 400GB(primary shards) for apm transaction indices and 700M documents, 300GB(primary shards) for apm span indices.
Number of primary shards are 20 for each indices.
Usually my elasticsearch node's CPU utilization is 20%~40%
It will really helpful if you tell me experience about hot warm architecture.
