 * Note that each chaining method returns a new ordering instance which is backed by the previous
 * instance, but has the chance to act on values <i>before</i> handing off to that backing instance.
 * As a result, it usually helps to read chained ordering expressions <i>backwards</i>. For example,

          spec:
            description: BFDProfileSpec defines the desired state of BFDProfile.
            properties:
              detectMultiplier:
                description: Configures the detection multiplier to determine packet
                  loss. The remote transmission interval will be multiplied by this
                  value to determine the connection loss detection timer.

* Microsoft SQL Server，等等其它数据库

在此示例中，我们将使用**SQLite**，因为它使用单个文件并且 在Python中具有集成支持。因此，您可以复制此示例并按原样来运行它。

稍后，对于您的产品级别的应用程序，您可能会要使用像**PostgreSQL**这样的数据库服务器。
