> In the lower-level Processor API we allow users to pass in a customizable StreamPartitioner when creating a new sink processor node to the topology:
> {code}
> builder.addSink(String name, String topic, StreamPartitioner partitioner, String... parentNames));
> {code}
> This StreamPartitioner allows users to specify any partitioning schemes based on record values instead of using the default behavior of hashing on the message key; but it is not exposed in the higher-level Streams DSL.
> We can add this parameter to the Streams DSL as well:
> {code}
> KStream#to(String topic, StreamPartitioner partitioner);
> KTable#to(String topic, StreamPartitioner partitioner);
> {code}
