Sorter transformation

Sorter transformation

Use a Sorter transformation to sort data in ascending or descending order, according to a specified sort condition. You can configure the Sorter transformation for case-sensitive sorting and for distinct output. The Sorter transformation is a passive transformation.
You can use the Sorter transformation to increase performance with other transformations. For example, you can sort data that passes through a Lookup or an Aggregator transformation configured to use sorted incoming fields.
When you create a Sorter transformation, specify fields as sort conditions and configure each sort field to sort in ascending or descending order. You can use a parameter for the sort condition and define the value of the parameter when you configure the
mapping
task.
