Cross-cluster search is now supported on existing Amazon OpenSearch Service domains
Amazon OpenSearch Service now offers support for cross-cluster search on existing domains. Cross-cluster search enables you to perform searches and aggregations across multiple domains with a single query or from a single OpenSearch Dashboard interface. With this feature, you can separate heterogeneous workloads into multiple domains, which provides better resource isolation, and the ability to tune each domain for their specific workloads to improve efficiency and reduce costs.

Previously, you had to create a new domain to use cross-cluster search. With this release, you can continue to use your existing domains to take advantage of cross-cluster search. Cross-cluster search lets customers set up a secure connection between domains. Domain owners have the flexibility to create, view, remove and monitor connections to or from their domains. All cross-cluster search requests between domains are encrypted and can be secured with fine-grained access policies. Cross-cluster search works across accounts within a single Region.
Cross-cluster search is available for Amazon OpenSearch Service across 26 Regions globally. Please refer to the AWS Region Table for more information about OpenSearch Service availability.
