Custom Aggregator Types for Pivot Tables

Pivot analysis tables can perform aggregation calculations on pivot table metrics through the aggregationRules configuration item in the dataConfig. In addition to the built-in aggregation types such as SUM, COUNT, AVERAGE, MAX, and MIN, custom aggregation types are also supported. To use custom aggregation types, you need to first define a custom aggregation class that inherits from the built-in Aggregator class, register it to VTable, and then implement the aggregation logic in the custom aggregation class.
