If the SynchronousInputID property is zero, the output is asynchronous. This means that the component developer must add the rows that the component receives in the input buffer that is received in the ProcessInput method to the output buffer that was received during PrimeOutput.
Conversely, if SynchronousInputID contains the ID of an IDTSInput100 object, PrimeOutput is not called for the component, and the data flow task automatically adds the rows from the input buffer to the output buffer of the component.
