抱歉,如果我在错误的地方发布了这个。我很欣赏这是一个很难回答的问题,因为有太多的变量,但任何建议或指针都会非常感激。
我们有一个非常大、笨重、设计糟糕的立方体。这是一种可怕的“一个立方体来统治他们”类型,如下所示。请注意,名称可能会出卖我工作的地方等的维度已被混淆。
作为一般经验法则,我想要了解的是一个多维数据集可以容纳多少数据。我(和几位专家,我并不声称自己是其中之一!)已向管理层表示,如果他们继续在当前级别向多维数据集添加数据(和属性),它将失败。我们想要的是一种方法来确定这是否会是今年、明年、本月等……是的,我知道这不会有一个确切的公式答案。任何指南都会非常有帮助,因为我在网上找不到任何指南;只有构建的最佳实践,我已经知道这不符合那个!我正在尝试获得预算批准以重新设计它,因此问题...
