I am wondering if nodes belonging to an AWS ElasticSearch Cluster can be assigned specific Roles ? For ex : For Cluster Stability and Consistency reasons, I may want 2 nodes in my 10 node ElasticSearch Cluster to be dedicated to serving : Ingest and Transform roles. Is that doable with AWS ElasticSearch ? Look forward to your response. Thanks and regards, Deepak ---

i found, if only 2 nodes, ingest node should be data node
