You can select either gp2 or gp3 as the AWS EBS SSD volume type for all clusters in a Databricks workspace. Databricks recommends you use gp3 for its cost savings compared to gp2. For technical information about gp2 and gp3, see Amazon EBS volume types.
By default, the Databricks configuration sets the gp3 volume’s IOPS and throughput IOPS to match the maximum performance of a gp2 volume with the same volume size.
To switch the Amazon EBS volume type from gp2 to gp3 for all clusters in a workspace, do the following:
Ensure that you have sufficient quotas for gp3 volumes and gp3 storage modifications. Consider using your current gp2 quotas as a guideline. For more information, see Amazon Elastic Block Store endpoints and quotas.
Sign in to the Databricks workspace as a Databricks admin.
Access the workspace admin settings.
On the Workspace Settings tab, in the Cluster section, enable EBS SSD gp3.
