const controlledCluster = require('controlled-cluster');

const processes = [
  (callback) => {
    console.log("running child process");
    setTimeout(() => {
      //do your work here
      let error = false;
      callback(error)
    }, 1000)
  },
  (callback) => {
    console.log("running child process");
    setTimeout(() => {
      //do your work here
      let error = false;
      callback(error)
    }, 1400)
  },
  (callback) => {
    console.log("running child process")
    setTimeout(() => {

      let error = false;
      callback(error)
    }, 2000)
  }
