Informatica 9.1：如果您将排序的输入传递给聚合器，那么它会给出排序的输出还是随机的？
Informatica 9.1: If you pass sorted input to Aggregator then does it gives sorted output or it's random?
在 Informatica 9.1 未分区映射中，我使用的是排序聚合器，之后有一个连接器；我可以让我的 joiner 成为排序的 joiner 吗？
这里的问题是，如果您将排序的输入传递给聚合器，那么从中获得排序输出的机会有多大？
高级转换指南 中讨论了此类场景。请注意以粗体突出显示的点。
When you add transformations between the sort origin and the Joiner
transformation, use the following guidelines to maintain sorted data:
Do not place any of the following transformations between the sort
origin and the Joiner transformation:
Custom
Unsorted Aggregator
Normalizer
Rank
Union transformation
XML Parser transformation
XML Generator transformation
Mapplet, if it contains one of the above transformations
You can place a sorted Aggregator transformation between the sort
origin and the Joiner transformation if you use the following guidelines:
Configure the Aggregator transformation for sorted input.
Use the same ports for the group by columns in the Aggregator transformation as the ports at the sort origin.
The group by ports must be in the same order as the ports at the sort origin.
When you join the result set of a Joiner transformation with
another pipeline, verify that the data output from the first Joiner transformation is sorted.
Tip: You can place the Joiner transformation directly after the sort
origin to maintain sorted data.
是的，输出已排序，您可以使用已排序的输入将其连接到连接器。
这是 Informatica 的行为与 Oracle 略有不同的一个实例。在 SQL 中，如果您传递已排序的输入并进行分组，则输出可能不一定已排序。
