yaml - 使用flux YAML，如何在Storm拓扑中提及螺栓的任务数量？

Question

请参阅这个 Storm-flux YAML 的片段：

## spout definitions
spouts: 
#spouts- Start
  - id: "perform-spout"
    className: "org.apache.storm.kafka.KafkaSpout"
    parallelism: 2
    constructorArgs:
      - ref: "PerformSpoutConfig"
#spouts- End  
   
## bolt definitions
bolts: 

#bolt - Start    
  - id: "perform-bolt"
    className: "com.cc.adv.asp.test.KafkaPerformanceBolt"
    parallelism: 2      
#bolt - End    

使用这个脚本，Storm-UI 显示No. of executors=No。的任务。请建议如何指定编号。Flux YAML 中的任务？提前致谢。
