Resizing your database
Scale up databases based on your needs. You may need to increase 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.
Scaling considerations
-
Scaling up has billing implications.
-
Only a database owner can resize a database.
-
You can’t scale down databases.
-
You can’t resize databases running on the Developer tier.
-
You can’t modify the compute size of existing databases.
Scaling up has billing implications. Scaling down is not supported. For assistance with scaling down, contact DataStax Support. |
Scale up a database
You can increase a database by a maximum of three CU at a time. You can resize a database multiple times if you need additional CUs. A database can’t have more than 20 CUs total.
-
In the Astra Portal, go to Databases.
-
Locate the database that you want to scale up, click
More, and then select Expand CUs. -
Modify the number of CUs for the database.
The total amount of storage and estimated cost changes dynamically based on the number of CUs entered.
-
To start resizing the database, click Expand, and then click Yes to confirm the increase.
The database enters Resizing status while scaling up. The database remains semi-active while resizing, but you have limited administrative functions. Once resizing is complete, the database returns to Active status.
