Two streams that are unrelated in data, but need to be sequential

[mikebundy]

First, I appreciate this library very much. Thank you for all this hard work.

I hope my question is a noob one, but I haven't found any definitive answer. I have two streams (stream1 and stream2). Stream 1 and Stream 2 work with different data, so there isn't a natural chaining of events from one to the other. However, I do want to make sure that stream1 finishes before stream2 starts.

For example, in SSIS, there is the Data Flow panel which defines how the data set will move and change from place to place, but there is also the Control Flow panel which orders and sequences the individual data flows. Etl.Net seems to focus on the Data Flows portion, but how should I be thinking about implementing Control Flow? Are there any examples that would show me the proper patterns to follow?

Thank you so much,
Mike
