Switch stage
The Switch stage is a processing stage that takes a single data set as input and assigns each input row to an output data set based on the value of a selector field.
The Switch stage can have a single input link, up to 128 output links and a single rejects link.
The Switch stage performs an operation analogous
to a C switch statement, which causes the flow of control in a C program
to branch to one of several cases based on the value of a selector
variable. Rows that satisfy none of the cases are output on the rejects
link.
The stage editor has three pages:
- Stage Page. This is always present and is used to specify general information about the stage.
- Input Page. This is where you specify the details about the single input set from which you are selecting rows.
- Output Page. This is where you specify details about the processed data being output from the stage.
