Amazon OpenSearch Service now supports in-place volume increases for all volume sizes

Amazon OpenSearch Service now extends in-place cluster volume size increases to volumes exceeding 3 TiB. With this enhancement, you can scale storage capacity across all volume sizes without requiring a blue/green deployment.

Previously, you could perform volume increases up to 3 TiB on your clusters without a blue/green deployment. This release removes that limitation, making it easier for you to scale up quickly even beyond 3 TiB when required. Domains that already have a volume size above 3 TiB will require a blue/green deployment the first time a volume increase is made; subsequent volume increases will not require a blue/green deployment.

Decreasing storage volume size, or making volume increases within short intervals, will still require a blue/green deployment. You can use the dry-run option to check whether your change requires a blue/green deployment.

This feature is available in all AWS Commercial and AWS GovCloud (US) Regions where Amazon OpenSearch Service is available. See here for a full list of our Regions. To learn more about Amazon OpenSearch Service configurations, visit the documentation page.
