I have a question about the "snapshot_identifier" property of aws.rds.Instance.
I've just created a cluster from a snapshot by populating "snapshot_identifier" resource when creating the cluster.
Do I need to keep the "snapshot_identifier" populated with the snapshot's name (and therefore, the snapshot itself) for subsequent changes to the cluster?
What happens if the "snapshot_identifier" resource is blanked (snapshot_identifier="") for subsequent changes to the cluster?

It is used when creating or restoring a snapshot, as opposed to when deploying via Pulumi. Any time you trigger either of those actions, that field is used by RDS, not Pulumi.
