 def create_table_from_snapshot( self, parent, table_id, source_snapshot, retry=google.api_core.gapic_v1.method.DEFAULT, timeout=google.api_core.gapic_v1.method.DEFAULT, metadata=None, ):
 """ Creates a new table from the specified snapshot. The target table must not exist. The snapshot and the table must be in the same instance. Note: This is a private alpha release of Cloud Bigtable snapshots. This feature is not currently available to most Cloud Bigtable customers. This feature might be changed in backward-incompatible ways and is not recommended for production use. It is not subject to any SLA or deprecation policy. Example: Args: parent (str):
 The unique name of the instance in which to create the table. Values are of the form ``projects/<project>/instances/<instance>``. table_id (str):
 The name by which the new table should be referred to within the parent instance, e.g., ``foobar`` rather than ``<parent>/tables/foobar``. source_snapshot (str):
 The unique name of the snapshot from which to restore the table. The snapshot and the table must be in the same instance. Values are of the form ``projects/<project>/instances/<instance>/clusters/<cluster>/snapshots/<snapshot>``. retry (Optional[google.api_core.retry.Retry]):
 A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]):
 The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]):
 Additional metadata that is provided to the method. Returns: A :class:`~google.cloud.bigtable_admin_v2.types._OperationFuture` instance. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid. """
