이 샘플에서는 프로젝트에 대한 Compute Engine 사용량 내보내기 버킷을 설정하고 검색하는 방법을 보여줍니다. 사용량 내보내기 버킷은 Compute Engine 사용량 보고서가 저장되는 Google Cloud Storage 버킷입니다. 사용량 보고서는 결제 및 비용 관리 목적으로 사용될 수 있습니다.

"""
Waits for the extended (long-running) operation to complete.
If the operation is successful, it will return its result.
If the operation ends with an error, an exception will be raised.
If there were any warnings during the execution of the operation
they will be printed to sys.stderr.
Args:
operation: a long-running operation you want to wait on.
verbose_name: (optional) a more verbose name of the operation,
used only during error and warning reporting.
timeout: how long (in seconds) to wait for operation to finish.
If None, wait indefinitely.
Returns:
Whatever the operation.result() returns.
Raises:
This method will raise the exception received from `operation.exception()`
or RuntimeError if there is no exception set, but there is an `error_code`
set for the `operation`.
In case of an operation taking longer than `timeout` seconds to complete,
a `concurrent.futures.TimeoutError` will be raised.
