   @Jackie-Jiang Do you have an idea why this is necessary? When I look at your 
example data, no transformation should be needed, just name fields 
dot-separated, e.g. query.userQuery as I did. Here is a small snippet of what 
`avro cat` prints for my data:
   ```
   {
     "query": {
       "userQuery": "picknick decke",
       "masterQuery": null,
       "mappingTime": -1
     },
     "kpis": {
       "clicks": 3,
       "checkout": 0,
       "cart": 10
     }
   }
   {
     "query": {
       "userQuery": "100243020",
       "masterQuery": null,
       "mappingTime": -1
     },
     "kpis": {
       "clicks": 1,
       "checkout": 0,
       "cart": 0
     }
   }
   {
     "query": {
       "userQuery": "foo",
       "masterQuery": bar,
       "mappingTime": 1617418890
     },
     "kpis": {
       "clicks": 10,
       "checkout": 1,
       "cart": 2
     }
   }
   ```
