Reconfiguring a database

This document explains how to reconfigure database resources using the PlanetScaleDB console.


This document assumes you have an existing PlanetScaleDB database. You can also create a new database.


Once you have a PlanetScaleDB database, you can reallocate resources for the database from the PlanetScaleDB console. This includes CPU, storage, memory, database instances, and analytics instances.

To reconfigure a database, complete the following steps:

  1. Open the Overview page for a cluster.
  2. Select a cluster.
  3. Click on the name of the database.
  4. Click Reconfigure.
  5. Modify the resource allocation.
  6. Click Resize Database.

Step 1: Open the Overview page for a cluster.

When you create a new cluster, this page opens automatically. Otherwise, log in to the PlanetScale console.

Step 2: Select a cluster.

Click on the name of the cluster where your database will run. This will open the overview for the cluster.

Step 3: Click on the name of the database.

Under Databases, click the name of the database you wish to reconfigure.

Step 4: Click Reconfigure.

Under Configuration, click the Reconfigure button.

Step 5: Modify the resource allocation.

In the Reconfigure Database pane, modify the resource allocation for the database. You can reallocate the following resources:

The Cost per instance calculator shows the hourly cost for the new configuration.

Storage reallocation takes a few seconds. CPU and RAM reallocation may take several hours.

PlanetScaleDB does not currently support decreasing the storage allocation for a database.

Step 6: Click Resize Database.

A message appears to confirm that the reconfiguration is successful.
