Question

我在mixpanel中有一个JQL。我设法得到以下格式的结果：

key, count1, count2, count3
a  ,     10,      0,      0
a  ,      0,      3,      0
a  ,      0,      0,      7
b  ,      2,      0,      0
b  ,      0,      3,      0
b  ,      0,      0,      5

我希望得到如下结果：

key, count1, count2, count3
a  ,     10,      3,      7
b  ,      2,      3,      5

换句话说：groupBy（['key']，WHAT_REDUCER_DO_I_NEED ???）

Answer 1

您可以在groupBy语句中使用多个reducer，如下所示

.groupBy(['key'], [
    mixpanel.reducer.sum('count1'),
    mixpanel.reducer.sum('count2'),
    mixpanel.reducer.sum('count3')
])

Answer 2

  .groupBy(["key"], function(accumulators, events){
    var sum = {"count1":0,"count2":0,"count3":0};
    for (var i = 0; i < accumulators.length; ++i) {
      sum["count1"] += accumulators[i]["count1"];
      sum["count2"] += accumulators[i]["count2"];
      sum["count3"] += accumulators[i]["count3"];
    }
    for (i = 0; i < events.length; ++i) {
      var event = events[i];
      sum["count1"] += event["count1"];
      sum["count2"] += event["count2"];
      sum["count3"] += event["count3"];
    }
    return sum;
  })

如何在mixpanel JQL中按columnA和sum columnB，columnC进行分组
