Automate index management with Amazon Elasticsearch Service
Amazon Elasticsearch Service now enables you to automate recurring index management activities. In the past you had to use additional tools to manage the data lifecycle inside Elasticsearch. For example, customers often setup daily indexes for their operational logs, roll them over nightly, and after 30 days delete the oldest index. With Index State Management, you can now create a policy that will automate these operations based on index age, size, and other conditions, all from within your Amazon Elasticsearch Service domain.
