> IterativeCondition only exposes the filter interface. For the aggregation
> operation in the condition, since the condition may be called multiple times
> in the NFA process, an event may cause the custom aggregation state in the
> condition to be updated multiple times, for example, filters goods with a
> total of more than 1000 orders in the past 10 minutes. AggregateFunction is
> introduced in IterativeCondition to initialize and maintain aggregation state.
