Amazon OpenSearch Serverless Scales to 10,000 Collections Per Group
Amazon OpenSearch Serverless just bumped its collection limit from 1,500 to 10,000 per collection group, letting you pack way more multi-tenant workloads into a single shared compute pool. This means better cost efficiency and resource utilization across all AWS Regions where nextgen OpenSearch Serverless is available—perfect for scaling those tenant-per-collection architectures without spinning up extra infrastructure.
