Redshift permissions
When you create a Redshift connection in Prophecy, access permissions are tied to the credentials you use. This is because Prophecy uses your credentials to execute all data operations, such as reading from or writing to tables. To fully leverage a Redshift connection in Prophecy, you need read and write access to the tables you use.
Sharing connections within teams
Connections in Prophecy are stored within fabrics, which are assigned to specific teams. Once a Redshift connection is added to a fabric, all team members that have access to the fabric can use the connection in their projects. No additional authentication is required—team members automatically inherit the access and permissions of the stored connection credentials.
Be mindful of the access level granted by the stored credentials. Anyone on the team will have the same permissions—including access to sensitive data if allowed.
To manage this securely, consider creating a dedicated fabric and team for high-sensitivity connections. This way, only approved users have access to those credentials.
Fetching data
Prophecy fetches data from Redshift connections in the following ways:
-
When you browse a Redshift connection in the Environment browser, Prophecy fetches data on demand as you expand folders. You can manually refresh the Environment browser to see updated files.
-
When a pipeline runs, Source gems will read the latest available version of the data. If the schema of your data in Redshift changes, Prophecy will automatically use the new schema.
