   I mean it would be nice to have reproducible ids. So no matter how many 
times I run SkyWalking, it always returns the same segments/trace ids as long 
as I do exactly the same processing. As far as I know, this is called 
"reproducible random". I hacked it together like this 
https://github.com/BFergerson/skywalking-java/commit/310c097bd1450b076dd14446eb01ec07dbae3ab0,
 but it could be done smarter.
   
   This made it easy to debug since segment/trace ids always started at 1 and 
incremented each time I debugged. Eventually, I realized each span was getting 
a new segment/trace id and that was the problem to solve. When I had it fixed, 
the trace ids where all the same number.
   
   It might make sense to use a reproducible random for test scenarios so you 
could validate the expected segment/trace ids. Just a thought.
