例句
Transitions within states should normally be synchronous, since there is no change of owner.
状态间的转换通常应该是同步的，因为所有者没有改变。
For example, you might have a synchronous replica on another machine in the same data center, and an asynchronous replica on a machine in another data center.
例如，您可以在同一个数据中心的另一台机器上选择同步复制，而在另一个数据中心的机器上选择异步复制。
