> A common task is to summarize numerical data for different groups. Having a `statsByKey`
method would simplify this so the user would not have to write the aggregators for all the
statistics or manage collecting by key and computing individual StatCounters.
> This should be a straightforward addition to PySpark. I can look into adding to Scala
and R if we want to maintain feature parity.
