Amazon OpenSearch Serverless now supports Collection Groups, a new capability that enables you to share OpenSearch Compute Units (OCUs) across collections with different AWS KMS keys. This new capability delivers enhanced cost optimization through a shared compute model that reduces overall OCU expenses while maintaining collection-level security and access controls. Additionally, Collection Groups introduce the ability to specify minimum OCU allocations alongside maximum OCU limits, allowing you to provision compute capacity upfront at startup for more predictable performance.
Collection Groups are particularly valuable for multi-tenant workloads where different tenants require data encryption with separate KMS keys while still benefiting from shared compute resources. By grouping collections together, you can optimize OCU utilization across workloads, reduce costs through resource sharing, and maintain the security isolation required by different encryption keys. The minimum OCU setting ensures your collections have guaranteed baseline capacity from the moment they start, eliminating cold start delays and providing consistent performance for latency-sensitive applications.
Collection groups are available in all regions where Amazon OpenSearch Serverless is currently available. To learn more about configuring and managing collection groups, visit the Amazon OpenSearch Serverless documentation.
