If an error occurs during the LUW, it might be too late to reverse the updates; or, more typically, reversing the update can lead to cascading problems.

如果在LUW执行中发生错误，此时反转更新可能为时已晚；或者更常见的是，反转更新会导致级联问题。

Further updates are then processed in a cascading fashion, just like in a spreadsheet: maps that depend on the updated metrics update their targets, and so forth.

然后以级联方式处理进一步的更新，就像在电子表格中一样：依赖更新后的度量的映射将运行，然后依赖其目标的映射将运行，以此类推。
