Creates multiple new entities in the specified entity type (extends the
existing collection of entries).

Operation <response: ``google.protobuf.Empty``>

Example:
    >>> import dialogflow_v2beta1
    >>>
    >>> client = dialogflow_v2beta1.EntityTypesClient()
    >>>
    >>> parent = client.entity_type_path('[PROJECT]', '[ENTITY_TYPE]')
    >>>
    >>> # TODO: Initialize ``entities``:
    >>> entities = []
    >>>
    >>> response = client.batch_create_entities(parent, entities)
    >>>
    >>> def callback(operation_future):
    ...     # Handle result.
    ...     result = operation_future.result()
    >>>
    >>> response.add_done_callback(callback)
    >>>
    >>> # Handle metadata.
    >>> metadata = response.metadata()

Args:
    parent (str): Required. The name of the entity type to create entities in. Format:
        ``projects/<Project ID>/agent/entityTypes/<Entity Type ID>``.
    entities (list[Union[dict, ~google.cloud.dialogflow_v2beta1.types.Entity]]): Required. The collection of entities to create.
        If a dict is provided, it must be of the same form as the protobuf
        message :class:`~google.cloud.dialogflow_v2beta1.types.Entity`
    language_code (str): Optional. The language of entity synonyms defined in ``entities``. If not
        specified, the agent's default language is used.
        [More than a dozen
        languages](https://dialogflow.com/docs/reference/language) are supported.
        Note: languages must be enabled in the agent, before they can be used.
    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.dialogflow_v2beta1.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.
