Amazon OpenSearch Service now lets you update cluster manager (master node) instance type or instance count without requiring a blue/green deployment, helping you complete the updates faster with the least potential disruption to your cluster operations and without involving any data movement.
Previously, when you updated the cluster manager instance type or instance count on your domain, OpenSearch Service used a blue/green deployment mechanism to make the change. While blue/green deployments are meant to avoid any disruption to your clusters, as the deployment utilizes additional resources on the domain, it is recommended that you perform them during low traffic periods. Now, you can update cluster manager instance type or cluster manager instance count without requiring a blue/green deployment, ensuring that these updates can complete faster, while avoiding any potential disruption to your cluster operations. In cases wherein you modify both cluster manager instance type and count, OpenSearch Service will still use a blue/green deployment to make the change. You can use the dry-run option to check whether your change requires a blue/green deployment.
The improved cluster manager update experience is now available in all AWS Regions where Amazon OpenSearch Service is available. Please refer to the AWS Region Table for more information about Amazon OpenSearch Service availability.
