Enabling or disabling Auto-Tune - Amazon OpenSearch Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Enabling or disabling Auto-Tune

OpenSearch Service enables Auto-Tune by default on new domains. To enable or disable Auto-Tune on existing domains, we recommend using the console, which simplifies the process. Enabling Auto-Tune doesn't cause a blue/green deployment.

You currently can't enable or disable Auto-Tune using Amazon CloudFormation.

To enable Auto-Tune on an existing domain

  1. Open the Amazon OpenSearch Service console at https://console.aws.amazon.com/aos/home.

  2. In the navigation pane, under Domains, choose the domain name to open the cluster configuration.

  3. Choose Turn on if Auto-Tune isn't already enabled.

  4. Optionally, select Off-peak window to schedule optimizations that require a blue/green deployment during the domain's configured off-peak window. For more information, see Scheduling Auto-Tune enhancements.

  5. Choose Save changes.

To enable Auto-Tune using the Amazon CLI, send an UpdateDomainConfig request:

aws opensearch update-domain-config \
  --domain-name my-domain \
  --auto-tune-options DesiredState=ENABLED
