AOSCOST02-BP03 Use the warm storage tier to optimize storage for a significant amount of read-only data
Reduce costs, improve query performance, and enhance domain stability by storing a significant amount of read-only data in the warm tier.
Level of risk exposed if this best practice is not established: Low
Desired outcome: The warm tier is used in OpenSearch Service to store a significant amount of read-only data, reducing costs while maintaining data availability.
Benefits of establishing this best practice:
-
Reduced costs due to optimized storage utilization
-
Improved query performance through optimized data retrieval
-
Enhanced domain stability by avoiding unnecessary resource utilization
Implementation guidance
Use data lifecycle management policies to move large amounts of read-only data to UltraWarm tier for low-latency queries and reduced costs.
To optimize costs and performance in Amazon OpenSearch Service, you can use the UltraWarm tier for storing a significant amount of read-only data.
Implementation steps
-
Log in to the AWS Management Console
. -
Navigate to the Amazon OpenSearch Service console.
-
Select the domain name and choose Actions, then Edit cluster configuration.
-
Enable UltraWarm:
-
In the Cluster configuration section, look for the option Enable warm data nodes located in the Warm and cold data storage box.
Note
You need to have dedicated leader nodes in your domain to be able to use warm and cold storage.
-
Toggle on the option to enable UltraWarm nodes.
-
Select the Instance type.
-
Set the number of warm data nodes (it is required to have a minimum of three).
-
-
After configuring the settings, review your setup and choose Create (for a new domain) or Save changes (for an existing domain).
