    Description

      To set a shard number that will be for controlling the size per shard properly, we need to estimate cube size through accumulating all dimension and measure size roughly before building a cube. But the way of calculating the percentile measure is inaccurate currently and cause too many partitions for cube storage. Furthermore, it may affect the performance of SQL query.
