What is the difference between the Filter stage and the Switch stage?

Functionally, they seem to do the same thing, unless I am missing something. I know the Switch stage uses a C style case statement, so in terms of performance, is one better than the other? Are there any other considerations to take?

Thanks in advance.

There are two main differences, and probably some minor ones as well. The two main differences are as follows.

• The Filter stage can send one input row to more than one output link. The Switch stage can not - the C switch construct has an implicit break in every case.
  
  The Switch stage is limited to 128 output links; the Filter stage can have a theoretically unlimited number of output links. (Note: this is not a challenge!)
