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. You can scale storage capacity across all volume sizes without requiring a blue/green deployment for subsequent increases beyond 3 TiB. Domains with a volume size above 3 TiB will require a blue/green deployment for the first increase. Decreasing storage volume size or making volume increases within short intervals still requires a blue/green deployment. Use the dry-run option to check deployment requirements.

This feature is available in all AWS Commercial and AWS GovCloud (US) Regions where Amazon OpenSearch Service is available. For more information, visit the documentation page.
