Multiple Input Groups

Multiple Input Groups

The Workflow Manager places a partition point at a multiple input group Custom transformation that requires a single thread for each partition.
For example, consider the following mapping:
In this mapping, two Source Qualifier transformations connect to CT_Order_class, which connects to CT_Order_Prep.
  1. Partition Point
  2. Multiple input groups.
  3. Requires one thread for each partition.
  4. Does not require one thread for each partition.
CT_Order_class and CT_Order_Prep have multiple input groups, but only CT_Order_Prep requires one thread for each partition. The Workflow Manager creates a partition point at CT_Order_Prep.
