Amazon OpenSearch Service UltraWarm Node Icon

Amazon OpenSearch Service UltraWarm nodes are a cost-effective storage tier for your OpenSearch Service domains. They're designed for storing and quickly retrieving large volumes of historical data that you don't need immediate access to, but still want to query efficiently. Think of them as a fast, scalable archive for your less frequently accessed OpenSearch data, helping to reduce the overall cost of your cluster while maintaining fast query speeds for your frequently used data.
