allowed_persistence_regions
:noindex:
MutableSequence[str]
Optional. 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.
enforce_in_transit
:noindex:
bool
Optional. If true, allowed_persistence_regions is also
used to enforce in-transit guarantees for messages. That is,
Pub/Sub will fail Publish operations on this topic and
subscribe operations on any subscription attached to this
topic in any region that is not in
allowed_persistence_regions.
