Hello,
It seems like the documentation [0] about side in- and outputs has missed some
refactoring of the code. I can’t find Max.MaxIntFn() for example, but there is
a
new Max.ofIntegers() method that looks like it matches it.
I would love to improve the documentation via a pull-request, but I don’t
understand this concept well enough to feel confident doing so, yet.
My intention is to get a
PCollectionView<Long> numOfDays
Which holds the number of elements (days) of a given PCollection<DateTime>
dates,
and building it via a sum of counts (as a SingletonView).
Something that corresponds in my head to *wrong*:
dates.apply("Count", Count.globally().asSingletonView());
Is it possible to access the side input outside of a DoFn?
