 * `tags` - Databricks tags all endpoint resources with these tags.
 * `spot_instance_policy` - The spot policy to use for allocating instances to clusters: `COST_OPTIMIZED` or `RELIABILITY_OPTIMIZED`. This field is optional. Default is `COST_OPTIMIZED`.
 * `enable_photon` - Whether to enable [Photon](https://databricks.com/product/delta-engine). This field is optional and is enabled by default.
-* `enable_serverless_compute` - Whether this SQL warehouse is a serverless endpoint. If this value is true explicitly or through the default, you **must** also set `warehouse_type` field to `pro`.
+* `enable_serverless_compute` - Whether this SQL warehouse is a serverless endpoint. See below for details about the default values. To avoid ambiguity, especially for organizations with many workspaces, Databricks recommends that you always set this field explicitly.
 
-    - **For AWS**, Databricks strongly recommends that you always explicitly set this field. If omitted, the default is false for most workspaces. However, if this workspace used the SQL Warehouses API to create a warehouse between September 1, 2022 and April 30, 2023, the default remains the previous behavior which is default to true if the workspace is enabled for serverless and fits the requirements for serverless SQL warehouses. To avoid ambiguity, especially for organizations with many workspaces, Databricks recommends that you always set this field. If your account needs updated [terms of use](https://docs.databricks.com/sql/admin/serverless.html#accept-terms), workspace admins are prompted in the Databricks SQL UI. A workspace must meet the [requirements](https://docs.databricks.com/sql/admin/serverless.html#requirements) and might require an update its instance profile role to [add a trust relationship](https://docs.databricks.com/sql/admin/serverless.html#aws-instance-profile-setup).

A workspace must meet the [requirements](https://learn.microsoft.com/azure/databricks/sql/admin/serverless) and might require an update to its [Azure storage firewall](https://learn.microsoft.com/azure/databricks/sql/admin/serverless-firewall).
 
-    - **For Azure**, you must [enable your workspace for serverless SQL warehouse](https://learn.microsoft.com/azure/databricks/sql/admin/serverless). For Azure, if serverless SQL warehouses are disabled for the workspace, the default is `false`. If serverless SQL warehouses are enabled for the workspace, the default is `true`.
 * `channel` block, consisting of following fields:
   * `name` - Name of the Databricks SQL release channel. Possible values are: `CHANNEL_NAME_PREVIEW` and `CHANNEL_NAME_CURRENT`. Default is `CHANNEL_NAME_CURRENT`.
-* `warehouse_type` - SQL warehouse type.

Set to `PRO` or `CLASSIC` (default).  If you want to use serverless compute, you must set to `PRO` and **also** set the field `enable_serverless_compute` to `true`.
