Under Select your source type, choose Model and click Continue.

To configure a model as source:

1. Enter an optional description and specify the custom SQL query in Query section.
2. Click Run Query to fetch the data preview.
3. Select the Primary key to use a column that uniquely identifies your warehouse records.

You can set a primary key only after you run the SQL query successfully using the Run Query option.

RudderStack uses the primary key column for diffing in case of incremental syncs. You can generate it by:

• Generating your table with a primary key, OR
• Creating a table view

You can use a composite key in cases where one column cannot be considered as a primary key. For example, you can a declare a composite key of user_id and timestamp in SQL query of the model.

Finally, review and complete your source setup.
