Delete or discontinue PCU groups in Astra DB

When you no longer need a PCU group, your options for removing that group depend on the group’s workload type:

Discontinue committed capacity PCU group subscriptions

When a committed capacity (RCU-based) PCU groups is eligible for renewal, you can renew, modify, or discontinue the subscription.

This is the only time that you can decrease a group’s reserved capacity.

You must take action if you want to modify or cancel your subscription during the renewal period.

If a PCU subscription is eligible for automatic renewal, DataStax sends automatic renewal notifications 45 days, 14 days, and 48 hours prior to renewal.

If you take no action, the PCU subscription renews automatically with the same reserved capacity (RCU) commitment.

Delete flexible capacity PCU groups

The Astra DB PCU management features are available only for public preview to qualified participants. Development is ongoing, and the features and functionality are subject to change. This preview is governed by your Agreement and the DataStax Preview Terms.

This preview covers two sets of features:

  • Core PCU management: Create PCU groups, edit PCU groups, and view PCU group usage

  • Flexible capacity workloads: Select a workload type in the Astra Portal, park PCU groups, and delete PCU groups

DataStax grants access to each set of features separately. To inquire about access to these features, contact your DataStax account representative.

You can delete flexible capacity PCU groups at any time, if you no longer need those resources.

Deleting a PCU group doesn’t delete the databases assigned to the group.

  1. In the Astra Portal header, click Settings.

  2. In the Settings navigation menu, click the name of the current organization, and then select the organization where you want to delete a PCU group.

  3. In the Settings navigation menu, click Billing.

  4. In the Provisioned Capacity Unit groups section, find the PCU group that you want to delete.

  5. Optional: Click More, select View details, make a note of the group’s Scoped databases, and then close the PCU group details.

  6. Click More, and then select Delete.

    If this option isn’t available, make sure the group is a flexible capacity PCU group with a reserved capacity of zero. If these conditions are true, contact your DataStax account representative to confirm that you have access to the delete feature for PCU groups.

After you delete a PCU group, the group’s databases are moved to standard, on-demand capacity. If you want to keep these databases on provisioned capacity, you must add them to another PCU group.

If you delete a parked PCU group, all of the group’s databases are moved to standard, on-demand capacity, and then returned to Active status.

If you want to delete the group’s databases in addition to the PCU group, see Terminate Astra DB Serverless databases.
