HeatWave Release Notes
A resource principal consists of a temporary session token and secure credentials that enables the MySQL DB System to authenticate itself to other services. Using a resource principal to access services, the token stored with the credentials on HeatWave is only valid for the resources to which the dynamic group has been granted access. To use a resource principal, you or your tenancy administrator define the policies and a dynamic group that allows access to resources with a resource principal.
For HeatWave on OCI, see Resource Principals in the HeatWave on OCI Service Guide.
