Sort conditions

Sort conditions

In advanced mode, you can configure a sort condition to specify the sort fields and the sort order. The
mapping
task uses the sort condition to sort the data before the Java code runs.
The sort fields are one or more fields that you want to use as the sort criteria. Configure the sort order to sort data in ascending or descending order.
If you configure a sort condition for data that is grouped into partitions, the
mapping
task sorts the data in each partition.
When you specify multiple sort conditions, the
mapping
task sorts each condition sequentially. The
mapping
task treats each successive sort condition as a secondary sort of the previous sort condition. You can configure the order of sort conditions.
If you use a parameter for the sort condition, define the sort fields and the sort order when you run the mapping or when you configure the
mapping
task.
