How AWS OpenSearch Serverless define which data is gonna be hot or warm in a time series collection?

Hello,

In OpenSearch Serverless, data is stored in Amazon S3, which serves as the primary storage for indexes. There is no explicit designation of "hot" or "warm" tiers within the storage itself. OpenSearch Serverless automatically manages the lifecycle of data based on usage patterns. It dynamically scales the compute resources (OpenSearch Compute Units or OCUs) to handle ingestion and search workloads, without the need for manual provisioning or tuning.

Please let me know if you have additional questions!
