Scale databases up or down based on your needs. You may need to increase or decrease the capacity of your DataStax Astra DB database.If a database is growing quickly or exceeding capacity, add another capacity unit (CU) to expand the storage and capabilities of the database.

This information applies to only classic databases.

You can increase your database by a maximum of three CUs.Multiple resize operations are required to add more CUs beyond the maximum number.

Consider the following conditions when resizing databases:

  • You must be the owner of a database to resize it.
  • Databases can only be increased in size to add more CUs.
  • Databases running on the Developer tier cannot be resized.
  • You cannot modify the compute size of existing databases.

Procedure

  • Open a browser, navigate to Astra DB, and log in.
  • From the Dashboard page, select the overflow menu for the database you want to resize and select Expand CUs.
  • In the Expand CUs window, modify the number of CUs for your database.
  • Select Expand to begin resizing the database.
  • Confirm you want to expand your database to your specified size by selecting Yes.

You will receive a confirmation that you database is scheduled for expansion.Your database remains active while resizing, but you will have limited administrative functions.Your database status changes to Resizing until the resizing is complete.

You will receive an email when your database is successfully resized, along with a link to the database.
