# Create an Apache Iceberg File Federation Data Stream

Start the flow of data by creating a data stream for Apache Iceberg. The data stream creates a data lake object (DLO) in Data 360 that you can map to the Customer 360 Data Model to use across Data 360.

| User Permissions Needed |                      |
| ----------------------- | -------------------- |
| To create a connection: | Data Cloud Architect |

Before you begin:

- Make sure that the required Apache Iceberg connection is set up.

1.  In Data Cloud, on the Data Streams tab, click **New**.

2.  Under Other Sources, select the Apache Iceberg connection source, and click **Next**.

3.  From the dropdown menus, select the connection and database to use.

4.  Under **Schemas**, select the schema to use.

5.  From the **Available Objects**, select the objects you want to include.

6.  Click **Next**.

**note:** You can't choose objects listed under **In Use Objects**.

7.  Enter the object name and object API name. For more information, see [Data Lake Object Naming Standards](https://help.salesforce.com/s/articleView?id=data.c360_a_data_lake_object_naming.htm&type=5).

8.  Select the category to specify the type of data to ingest. For more information, see [Category](https://help.salesforce.com/s/articleView?id=data.c360_a_category.htm&type=5).

9.  Select a primary key to uniquely identify the incoming records. For more information, see [Primary Key](https://help.salesforce.com/s/articleView?id=data.c360_a_primary_key.htm&type=5).
10. Select the source fields you want to ingest and click **Next**. Fields with convertible data types are listed under Supported Fields.

**note:** Fields whose data types are not supported in Data 360 get listed under Unsupported Fields.

11. Select the relevant data space. Choose “Default” for data space if you don’t have any other data space provisioned in your org. For more information, see [Data Spaces](https://help.salesforce.com/s/articleView?id=data.c360_a_data_spaces.htm&type=5).
