> There is currently no way to configure the {{StreamsPartitioner}} used by auto-repartitioning when using the Kafka Streams DSL. The default {{StreamsPartitioner}} is always used.
> This can create a problem for users, whereby joining/aggregating with a stream/table that has been partitioned with a custom partitioner may not work as expected, if the user does not explicitly {{repartition()}} the stream first with the custom {{{}StreamsPartitioner{}}}.
