Coming soon: workspace, pool, and cluster tags propagate to DBU usage details and Azure VMs for better cost management reporting

On February 10th, we will release tag propagation to Azure Databricks usage details and Azure VMs. The new tag propagation feature combines Azure Databricks workspace tags (that is, resource group tags), pool tags, and cluster tags and propagates them to the Databricks DBU usage details and Azure VMs as resource tags. You will be able to see the combined tag information in the Azure Cost Management portal and in usage detail exports, giving you better visibility into Azure Databricks usage (total cost of ownership) and accurate attribution to business units and teams.

Azure Databricks and Azure Lighthouse can now live in the same subscription

January 29, 2020

All existing Azure Databricks workspaces have migrated from using Managed Locks to Deny Assignments. All new workspaces created will have Deny Assignments. This does not change any existing behavior, and the level of security remains the same. While you can onboard subscriptions that use Azure Databricks, users in the managing tenant can't launch Azure Databricks workspaces on a delegated subscription at this time.

SCIM API supports pagination for Get Users and Get Groups (Public Preview)

January 7-14, 2020: Version 3.9

The SCIM API now supports pagination for Get Users and Get Groups. When you specify the startIndex and count query parameters, SCIM will return a subset of users/groups. The startIndex parameter is the 1-based index of the first result. The count parameter is the maximum number of users or groups to return. This ensures scalability for the SCIM Client and simplifies SCIM calls for Azure Databricks admins. See Groups API.
