过滤器的改造是主动的，更新策略是被动的。
The filter is an active transformation, the update strategy passive.
Ramkumar - 你所说的“如果集成服务对待......”是什么意思？真的，正如你所说，如果过滤器处于活动状态，那么它就是活动的。我认为集成服务尚不可能根据具体情况选择将转型视为主动还是被动......
Ramkumar - What do you mean by saying, "if the integration service treats..." Really, as you said, if filter is active, its active. I dont think there is a possibility yet that integration service can chose to treat a transformation as active or passive on a case to case basis...
Ramkumar - “如果迭代服务对待......”是什么意思？
过滤器和更新策略均处于活动状态。根据定义，任何改变通过它的行数的转换都是活动的。过滤器 txfn 正是这样做的。
更新策略被认为是活动的，因为它更改了行类型。尽管它本身不会更改行数，但它标记要删除、插入或更新的行，从而产生相同的结果。
Ramkumar - what do you mean by "if itegration service treats ..."?
Filter as well update strategy are both active. By definition any transformation that changes the number of rows passing thru it is active. Filter txfn does exactly this.
Update strategy is considered active because it changes row type. Although it doesn't by itself change the number of rows, it marks the rows for delete, insert or update producing the same result.
