Equals_Operator :=expression==expression. Remarks expression Is any valid expression. If the expressions are not of the same data type, the data type for one expression must be implicitly convertible to the data
在Metric 的声明模块中,使用 type 字段声明聚合计算依赖的是一个字段;使用 ref 字段声明字段的唯一标识,同时对于聚合计算所使用字段,还支持虚拟列,比如在计算总耗时类指标时,可能在底表没有直接存储耗时字段,而是需要通过 end_time - start_time 计算得到。 Operator 用于声明支持数据表字段的聚合计算(原子指标),如...
