Boyang Chen updated KAFKA-7071:
-------------------------------
Description:
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.
