Description

Currently, google_alloydb_cluster doesn't implement a deletion protection flag (such as in google_sql_database_instance, for example). This may cause data loss in situations when the cluster is destroyed or replaced by mistake.

Please note that Terraform's own prevent_destroy flag may not be used with variables, so it would not be a full replacement of the deletion protection flag on the resource. See the linked issue.
