-  - You'll need wait for the initial synchronization job to end, check the job status in the dashboard and the logs in the Data Source `log` tab
-  - You can add/update/delete items in your DynamoDB table and check that the changes reproduce in the Data Source.
+- Check that everything is created as expected in the temporary Tinybird Branch, CI will automatically create it and name it like `tmp_ci_{PRid}`).

 - If everything is fine, merge and wait for CD. Now you should have your Data Source in the main Workspace, using the Connection, and the temporary CI Branch will be deleted.
