Good suggestion! Here are some extra points we need to consider: 1. In order to split on MV dimension, we need to flatten the record into multiple records, each with one element of the MV entry. This can lead to much higher storage cost 2. If there are multiple MV dimensions to be split, we need to store all the element combination for the record 3. When there is no filter on the MV dimension, we must use the star-node to answer the query. Star-node creation is also different for the MV dimension because we cannot simply aggregate all the records under all non-star-node -- This is an automated message from the Apache Git Service.
