How to zip multiple cardinalities of nested json arrays?

[cblanton]

We are trying to zip and expand several levels of nested json data. Here is an example of our json data. Below is an example of the desired output.

   {
     "level0": {
         "globalname": "TOP_A",
         "globalver": "1",
         "level1": { 
           "level2": [ 
               {
                "lvl2name": "LVL2A", 
                "warnings": { 
                    "totalcount": "26",
                    "rulebreakdown": [
                    { 
                      "rulecount": "2",
                      "rulename": "ruleA"
                    },
                    { 
                     "rulecount": "24",
                     "rulename": "ruleB"
                    }
                 ]
               }
              },

              {
                "lvl2name": "LVL2B", 
                "warnings": { 
                    "totalcount": 81,
                    "rulebreakdown": [
                    { 
                      "rulecount": "11",
                      "rulename": "ruleG"
                    },
                    { 
                     "rulecount": "67",
                     "rulename": "ruleR"
                    },
                    { 
                     "rulecount": "3",
                     "rulename": "ruleZ"
                    }
                 ]
               }
              }
           ]
          }
        }
    }

    {
      "level0": {
          "globalname": "TOP_D",
          "globalver": "1.5",
          "level1": { 
            "level2": [ 
                {
                 "lvl2name": "LVL6A", 
                 "warnings": { 
                     "totalcount": "2",
                     "rulebreakdown": [
                     { 
                       "rulecount": "2",
                       "rulename": "ruleAB"
                     }
                  ]
                }
               }

               {
                 "lvl2name": "LVL6D", 
                 "warnings": { 
                     "totalcount": "23",
                     "rulebreakdown": [
                     { 
                       "rulecount": "5",
                       "rulename": "ruleGG"
                     }
                     { 
                      "rulecount": "14",
                      "rulename": "ruleRG"
                    }
                    { 
                     "rulecount": "4",
                     "rulename": "ruleGZ"
                   }
                  ]
                }
               }
            ]
           }
         }
     }

This would be the desired output of these two events:

| spath {} output=root
| stats count by root
| spath input=root level0.level1.level2{} output=level2
| stats values(root) as root by level2
| spath input=level2 warnings.rulebreakdown{} output=rulebreakdown
| mvexpand rulebreakdown
| spath input=level2 warnings.totalcount output=totalcount
| spath input=rulebreakdown
| spath input=root level0 output=level0
| spath input=level0
| fields - level* root rulebreakdown

That's a lot of work.
