Print out the results of a stream while returning the original values.
Tracing a pattern is most commonly done by using the .trace method directly on the pattern like this:
| pattern |
printOn this stream (default: Post). |
| key |
when streaming events, post only this key. |
| printStream |
(describe argument here) |
| prefix |
string added to the printout to separate different streams. |
Original values
| inval |
