Changes Amazon Elasticsearch Service now offers fine-grained access control, which adds multiple capabilities to give tighter control over data. New features include the ability to use roles to define granular permissions for indices, documents, or fields and to extend Kibana with read-only views and secure multi-tenant support.
Changes UltraWarm storage provides a cost-effective way to store large amounts of read-only data on Amazon Elasticsearch Service. Rather than attached storage, UltraWarm nodes use Amazon S3 and a sophisticated caching solution to improve performance.

In Elasticsearch, these warm indices behave just like any other index. You can query them using the same APIs or use them to create dashboards in Kibana.
