1·In practice, buffering may occur at various other levels, such as on the hard disk itself, the controller, or the kernel disk drive device driver, so ours may not make much of a difference.
实际上，缓冲可能发生在其它不同的级别，例如硬盘本身、控制器或内核磁盘驱动设备驱动程序，所以我们的工作可能对性能影响不大。
2·If another log checkpoint record is encountered while it is in drain mode, it goes back to buffering mode.
如果服务器处于排出模式下时遇到另一条日志检查点记录，那么它会回到缓冲模式。
3·If ownership of data is simply split between members, then you will have greater data buffering but you have the potential of having transaction routing issues.
如果数据的所有关系可以简单地在成员之间划分，那么您将拥有更好的数据缓冲，但是有可能遇到事务路由问题。
4·For example, some allow you to create indexes on the data, while others have the capability to configure caching and buffering options.
例如，某些机制允许您在数据上创建索引，而其他机制能够配置缓存和缓冲选项。
5·When the secondary encounters a checkpoint, it enters a buffering mode.
当次要服务器遇到检查点时，它将进入一种缓冲模式。
