## Requirements

You will need:

* A Databricks account on [AWS](https://docs.databricks.com/getting-started/free-trial.html),
  [Azure](https://learn.microsoft.com/azure/databricks/getting-started/), or
  [GCP](https://docs.gcp.databricks.com/getting-started/index.html).

* A workspace within the Databricks account for [AWS](https://docs.databricks.com/admin/workspace/index.html),
  [Azure](https://learn.microsoft.com/azure/databricks/admin/workspace/), or
  [GCP](https://docs.gcp.databricks.com/admin/workspace/index.html).

* The workspace's URL. Get the workspace URL for
  [AWS](https://docs.databricks.com/workspace/workspace-details.html#workspace-instance-names-urls-and-ids),
  [Azure](https://learn.microsoft.com/azure/databricks/workspace/workspace-details#workspace-instance-names-urls-and-ids),
  or [GCP](https://docs.gcp.databricks.com/workspace/workspace-details.html#workspace-instance-names-urls-and-ids).

  Examples:

  * AWS: `https://<workspace-id>.cloud.databricks.com`
  * Azure: `https://adb-<workspace-id>.<random-number>.azuredatabricks.net`
  * GCP: `https://<workspace-id>.<random-number>.gcp.databricks.com`

  <Note>
    Do not add a trailing slash (`/`) to the workspace URL.
  </Note>

* The Databricks authentication details. For more information, see the documentation for
  [AWS](https://docs.databricks.com/dev-tools/auth/index.html),
  [Azure](https://learn.microsoft.com/azure/databricks/dev-tools/auth/),
  or [GCP](https://docs.gcp.databricks.com/dev-tools/auth/index.html).

  The following Databricks authentication types are supported:

  * Databricks OAuth machine-to-machine (M2M) authentication for\
    [AWS](https://docs.databricks.com/dev-tools/auth/oauth-m2m.html),
    [Azure](https://learn.microsoft.com/azure/databricks/dev-tools/auth/oauth-m2m), or
    [GCP](https://docs.gcp.databricks.com/dev-tools/auth/oauth-m2m.html).

    You will need the **Client ID** (or **UUID** or **Application** ID) and OAuth **Secret** (client secret) values for the corresponding service principal.
    Note that for Azure, only Databricks managed service principals are supported. Microsoft Entra ID managed service principals are not supported.

    The following video shows how to create a Databricks managed service principal:

  * Databricks personal access token authentication for
    [AWS](https://docs.databricks.com/dev-tools/auth/pat.html),
    [Azure](https://learn.microsoft.com/azure/databricks/dev-tools/auth/pat), or
    [GCP](https://docs.gcp.databricks.com/dev-tools/auth/pat.html).

    You will need the personal access token's value.

* The name of the parent catalog in Unity Catalog for
  [AWS](https://docs.databricks.com/catalogs/create-catalog.html),
  [Azure](https://learn.microsoft.com/azure/databricks/catalogs/create-catalog), or
  [GCP](https://docs.gcp.databricks.com/catalogs/create-catalog.html) for the volume.

* The name of the parent schema (formerly known as a database) in Unity Catalog for
  [AWS](https://docs.databricks.com/schemas/create-schema.html),
  [Azure](https://learn.microsoft.com/azure/databricks/schemas/create-schema), or
  [GCP](https://docs.gcp.databricks.com/schemas/create-schema.html) for the volume.

* The name of the volume in Unity Catalog for [AWS](https://docs.databricks.com/tables/managed.html),
  [Azure](https://learn.microsoft.com/azure/databricks/tables/managed), or
  [GCP](https://docs.gcp.databricks.com/tables/managed.html), and optionally any path in that volume that you want to access directly, beginning with the volume's root.

* The Databricks workspace user or service principal must have the following *minimum* set of privileges to read from or write to the
  existing volume in Unity Catalog:

  * `USE CATALOG` on the volume's parent catalog in Unity Catalog.
  * `USE SCHEMA` on the volume's parent schema (formerly known as a database) in Unity Catalog.
  * `READ VOLUME` and `WRITE VOLUME` on the volume.

  The following videos show how to create and set privileges for a catalog, schema (formerly known as a database), and volume in Unity Catalog.
