Adding Transformations to the Mapping

Adding Transformations to the Mapping

Add transformations to the mapping that maintain the order of the sorted data in a Joiner transformation.
You can place the Joiner transformation directly after the sort origin to maintain sorted data.
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:
    • Rank
    • Union
    • Unsorted Aggregator
    • Mapplet that contains one the preceding 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.
