Attributes

Name	Description
target_change_type	google.cloud.firestore_v1.types.TargetChange.TargetChangeType The type of change that occurred.
target_ids	Sequence[int] The target IDs of targets that have changed. If empty, the change applies to all targets. The order of the target IDs is not defined.
cause	google.rpc.status_pb2.Status The error that resulted in this change, if applicable.
resume_token	bytes A token that can be used to resume the stream for the given ``target_ids``, or all targets if ``target_ids`` is empty. Not set on every target change.
read_time	google.protobuf.timestamp_pb2.Timestamp The consistent ``read_time`` for the given ``target_ids`` (omitted when the target_ids are not at a consistent snapshot). The stream is guaranteed to send a ``read_time`` with ``target_ids`` empty whenever the entire stream reaches a new consistent snapshot. ADD, CURRENT, and RESET messages are guaranteed to (eventually) result in a new consistent snapshot (while NO_CHANGE and REMOVE messages are not). For a given stream, ``read_time`` is guaranteed to be monotonically increasing.
