Description
在非集群模式时,可以使用`ParamFlowRule.setDurationInSec`的方式控制统计窗口的时长,以实现例如10000次/小时,50次/分的这种QPH、QPM的需求。
但是在集群模式时,看源码发现durationInSec这个字段在`ClusterParamFlowChecker.acquireClusterToken`中并没有用到,校验时间的方式和单机模式也有所不同,所以在集群模式时只能通过QPS的方式去控制流量吗？还是有其他的方法
Contributor guide
Research direction
Read ParamFlowRule.setDurationInSec and ClusterParamFlowChecker.acquireClusterToken, then compare how duration-based timing is handled in cluster and non-cluster modes. Confirm the intended cluster behavior and add focused coverage for it; done means durationInSec affects cluster-mode validation or the limitation is clearly documented.
