allowedPersistenceRegions property
A list of IDs of Google Cloud regions where messages that are published to the topic may be persisted in storage.
Messages published by publishers running in non-allowed Google Cloud regions (or running outside of Google Cloud altogether) are routed for storage in one of the allowed regions. An empty list means that no regions are allowed, and is not a valid configuration.
Optional.
