Sybase ETL 4.9 includes the new Copy Splitter component, which unconditionally copies input data to each output port. The Copy Splitter component lets you write data to each output port without evaluating output port conditions. By default, the component has two output ports.
Using the Copy Splitter component eliminates the need to invoke JavaScript, and reduces the cost of condition evaluation, therefore improving performance.
See Chapter 5, “Components” in the Sybase ETL 4.9 Users Guide.
