> On of the goals of the Scala API is to not fall back on the configured default serializer, but let the compiler provide them through implicits.
> The aggregate method on KGroupedStream misses to achieve this goal.
> Compared to the Java API is this behavior very supprising, because no other stream operation falls back to the default serializer and a developer assums, that the compiler checks for the correct serializer type.
