Issue details

With PR pulumi/pulumi#19487 the Pulumi SDK allows to mark resources with RefreshBeforeUpdate: true so that Pulumi will perform a refresh on the resource regardless if the user has added --refresh to the pulumi command or not.

Because Terraform always performs a refresh on the state before calculating and differences and actions on resources, this feature is of great benefit for maintainers of wrapped Terraform providers because Terraform providers often rely on a refresh to be performed to trigger any (internal) updates on the managed resources. One example of this is the Pulumi Time provider, which wraps the Terraform Time provider. Practitioners often struggle when the time provider does not rotate, update, or change any resources because Pulumi did not perform a refresh.

If Terraform Bridge would provide support for RefreshBeforeUpdate those issues can be prevented easily by marking the relevant resources, so that a refresh cycle is always performed.

The feature is still exprimental but it should be easy to expose for use in the bridged providers. Thank you for filing!
