PartitionStartRecord(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A partition start record serves as a notification that the client should schedule the partitions to be queried. PartitionStartRecord returns information about one or more partitions.

Attributes
Name	Description
start_timestamp	google.protobuf.timestamp_pb2.Timestamp Start timestamp at which the partitions should be queried to return change stream records with timestamps >= start_timestamp. DataChangeRecord.commit_timestamps, PartitionStartRecord.start_timestamps, PartitionEventRecord.commit_timestamps, and PartitionEndRecord.end_timestamps can have the same value in the same partition.
record_sequence	str Record sequence numbers are unique and monotonically increasing (but not necessarily contiguous) for a specific timestamp across record types in the same partition. To guarantee ordered processing, the reader should process records (of potentially different types) in record_sequence order for a specific timestamp in the same partition.
partition_tokens	MutableSequence[str] Unique partition identifiers to be used in queries.
