Subject RE: counters in multistage pipeline
Date Wed, 25 Mar 2015 20:29:02 GMT
That would be quite handy if it could sum any counter as well.  Would be a good way to get
performance metrics out.

My guess is yes, it's okay to just sum the results, but I'll double check the code- I'm assuming
the counts are different in the different StageResults?

Nothing that does an automatic merge, but agree that it would be useful. Post a patch? Maybe
a new method on PipelineResult?

I have one DoFn that increments a counter (and a bunch of other DoFns that don’t use counters).
When my DoFn with counter runs in a MRPipeline that returns multiple StageResults, I notice
that my counter appears with a non-zero value in 2 StageResults. Is it correct to just sum
up these values? Is there any utility class to this automatically for all counters in PipelineResult?
