Add A Data Source
The first thing you'll want to do is connect at least one data source . You can add a new data source from the quick link in the navigation bar:
Or via the Data Source tab in your admin settings:
If you’re using the Hosted Redash service, you'll need to allow access from the IP address 220.127.116.11 in your database firewall/security groups (unless it’s publicly available).
We recommend using a user with read-only permissions for the database ( BigQuery is an exception).
