Scheduling Auto-Tune enhancements

Prior to February 16, 2023, Auto-Tune used maintenance windows to schedule changes that required a blue/green deployment. Maintenance windows are now deprecated in favor of the off-peak window, which is a daily 10-hour time block during which your domain typically experiences low traffic. You can modify the default start time for the off-peak window, but you can't modify the length.

Any domains that had Auto-Tune maintenance windows enabled before the introduction of off-peak windows on February 16, 2023 can continue to use legacy maintenance windows with no interruption. However, we recommend that you migrate your existing domains to use the off-peak window for domain maintenance instead. For instructions, see Migrating from Auto-Tune maintenance windows.

To schedule Auto-Tune actions the off-peak window

  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. Go to the Auto-Tune tab and choose Edit.

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

  5. Under Schedule optimizations during off-peak window, select Off-peak window.

  6. Choose Save changes.

To configure your domain to schedule Auto-Tune actions during the configured off-peak window, include UseOffPeakWindow in the UpdateDomainConfig request:

aws opensearch update-domain-config \
  --domain-name my-domain \
  --auto-tune-options DesiredState=ENABLED,UseOffPeakWindow=true,MaintenanceSchedules=null
