> When building a cube from Kafka topic, the first step is to sink the Kafka data to HDFS.
In today's implementation, it will persist all the fields of a message to disk. While in many
cases, only a couple of fields will be needed for cubing; Today's behavior wastes network
bandwidth and disk space.
