Amazon OpenSearch Service now lets you update cluster volume size, volume type, IOPS and throughput without requiring a blue/green deployment. This makes it easier for you to make changes to your EBS settings without having to plan upfront for a blue/green deployment.
Previously, when you updated volume size, volume type, IOPS and throughput on your cluster, 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 cluster, it is recommended that you perform them during low traffic periods. Now, you can update volume related cluster configuration without requiring a blue/green deployment, ensuring minimal performance impact to your online traffic and avoiding any potential disruption to your cluster operations.
This feature is available for OpenSearch Service clusters with current generation instances, and when the volume size per data node is within 3 TiB. You can use the dry-run option to check whether your change requires a blue/green deployment.
Support to update cluster volume without blue/green is available on Amazon OpenSearch Service clusters in all Amazon Web Services regions where Amazon OpenSearch service is available, including the Amazon Web Services China (Beijing) Region, operated by Sinnet and the Amazon Web Services China (Ningxia) Region, operated by NWCD. Please refer to the Region Table for more information about Amazon OpenSearch Service.
