Changing cluster state

This section details how to change the cluster state in Kyvos by adjusting the Query Engine capacity or cluster status (online/offline) at a specific time to temporarily override existing scaling schedules.

You can change the cluster capacity as required. This change comes into effect immediately and overrides any existing schedules or rules. 

Note

  • When you change the cluster state, the system enters a transition phase from one schedule to another. During this phase, you cannot modify the Query Engine capacity.

  • Once the transition phase is complete, you can change the cluster capacity as needed. 

  • Upon completion of the Change Cluster State schedule, the load-based rules will be implemented automatically if they have been saved. If no rules have been saved on the Load screen, the cluster will run using the Change Cluster State capacity.

To change the cluster state, perform the following steps. 

  1. Click the Change Cluster State link available in the Cluster Current State section. 
    The Change Cluster State dialog is displayed. 

     

  2. Every cluster capacity option is associated with a title. The associated title is displayed in the Title box when you select a required capacity option.
    For example, if you choose the capacity option as Full, the title associated with the Full cluster capacity option is displayed in the Title box. You can use the default title or change the title for that schedule as needed. 

  3. Select the date and time when you want to change the cluster state. 

Note

The difference between the end time and the current time cannot be less than an hour.

  1. Select whether the service should remain online or offline.

  2. Click to select a query engine capacity. 

  3. Click Change Now.
    The Schedule entry is displayed in the schedule.
