We are excited to announce that Amazon OpenSearch Serverless can now scan and search up to 10TB of time series data which includes one or more indexes within a collection. OpenSearch Serverless is a serverless deployment option for Amazon OpenSearch Service that makes it simple for you to run search and analytics workloads without having to think about infrastructure management. With the support for much larger datasets than before, you can further enhance unlocking valuable operational insights and make data driven decisions to troubleshoot application downtime, improve system performance, or identify fraudulent activities. 

OpenSearch Serverless’ compute capacity used for data ingestion, search and query are measured in OpenSearch Compute Units (OCUs). These OCUs are shared among various collections. To accommodate larger datasets, OpenSearch Serverless now supports 200 OCUs for indexing and search respectively, doubling from the previous limit of 100, including redundancy for AZ outages and infrastructure failures. You configure the maximum OCU limits on search and indexing independently to manage costs. You can also monitor real-time OCU usage with CloudWatch metrics to gain a better perspective on your workload's resource consumption.

The support for larger workloads and collections for OpenSearch Serverless Service is now available in 8 regions globally: US East (Ohio), US East (N. Virginia), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Frankfurt), and Europe (Ireland). Please refer to the AWS Regional Services List for more information about Amazon OpenSearch Service availability. To learn more about OpenSearch Serverless, see the documentation
