Yes. You can set your Panoply data warehouse as the destination for an ETL service.
To do that, you'll need the connection details provided for your data warehouse. Go to the BI Connection page to view your warehouse's connection details.
After your ETL tool ingests data into your Panoply account, you'll be able to query it using your favorite BI tool or use the Workbench page inside the Panoply platform.
