          Components: streams

Hey there, I was wondering whether it makes sense to specify number of partitions of the output topic from a repartition operation like groupBy, flatMap, etc. The current DSL doesn't support adding a customized repartition topic which has customized number of partitions. For example, I want to reduce the input topic from 8 partitions to 1, there is no easy solution but to create a new topic instead.
