Use the simple form to manage compute
Important
This feature is in Public Preview.
This article explains how to access and use the new simplified compute UI to create and edit all-purpose and job compute.
Requirements
To access the simple compute form, your workspace must be enabled for the dedicated group cluster Public Preview.
Enable the simple form UI
After your workspace has been enabled for the dedicated group cluster Public Preview, you can toggle on the simple form:
In the workspace sidebar, click Compute.
Click the Create compute button or select an existing compute resource.
Toggle on the Simple form.
This toggle is also available when you create a new job compute in the Jobs UI.
Overview of updated settings
The simple form UI includes updates to several compute settings to make the compute creation process easier for users. These updates include:
- Policy selection
- Machine learning runtime checkbox
- Node type selection
- Access mode updates
- Removed the credential passthrough setting
- Removed the on-demand/spot instance slider
Policy selection
The Policy dropdown setting has improved to allow changing between policies without resetting the form.
Machine learning runtime checkbox
As a UI update, you can now check the Machine learning checkbox to switch to the machine learning version of your selected Databricks Runtime.
Node type selection
The multi-node setting has been removed from the UI. Compute is multi-node by default. To switch your compute to a single node, select the Single node checkbox in the Performance section.
When you switch to single-node compute, the custom tag ResourceClass:SingleNode and the necessary single-node Spark config are applied in the backend, not in the UI.
The new form also allows you to toggle the Single node setting on existing compute resources.
Additionally, the Driver type setting has moved under the Advanced performance section and defaults to Auto (formerly called Same as worker).
Access mode updates
The compute’s access mode, which dictates who can use the resource, has been moved under the Advanced settings.
Access mode selection is now Auto by default, meaning the access mode will automatically be chosen for you based on your selected Databricks Runtime. Machine learning runtimes and Databricks Runtimes lower than 14.3 default to Dedicated, otherwise Standard is used.
To manually select the access mode, click Manual then select the access mode using the dropdown menu.
Access mode naming updates
The access mode names have been updated in the following ways:
- Shared access mode is now Standard.
- Single user access mode is now Dedicated and can be assigned to single user or group.
- Additional access modes such as No isolation shared are marked as Legacy (not recommended).
Removed the credential passthrough setting
Credential passthrough is a legacy access mode. As such, the credential passthrough setting has been removed from the compute UI.
Removed the on-demand/spot instance slider
The spot instance slider has been removed. The simple form includes a Use spot instances checkbox in the Advanced performance section.
You can still specify the composition of on-demand and spot instances using the Clusters API.
