Even if the individual dimensions themselves are relatively small, the Cartesian join grows exponentially with each addition of a dimension.
即使单个维度相对较小,随着每个维度的加入,笛卡尔连接也会成倍增长。
The Cartesian join is reduced by the filters found in the join expressions from each dimension to the fake fact.
由于伪事实的每个维度中的连接表达式的过滤,笛卡尔连接结果缩小了。
If the Framework Manager model does not apply a form of filtering on the dimension query subjects, large Cartesian joins may be attempted.
如果Framework Manager模型没有在维度查询主题上应用过滤,可尝试大型笛卡尔积可能出现。
