When a mapping contains a Custom transformation, a Java transformation, SQL transformation, or an HTTP transformation, you can edit the following partitioning information:
Add multiple partitions.
You can create multiple partitions when the Custom transformation allows multiple partitions.
Create partition points.
You can create a partition point at a Custom transformation even when the transformation does not allow multiple partitions.
The Java, SQL, and HTTP transformations were built using the Custom transformation and have the same partitioning features. Not all transformations created using the Custom transformation have the same partitioning features as the Custom transformation.
When you configure a Custom transformation to process each partition with one thread, the Workflow Manager adds partition points depending on the mapping configuration.
