Mapping for object with dynamic keys

[luckyb56 (ab)]

Have a document like this:

  {
       "stats": {
         "fruits.v:apple": 30,
         "fruits.v:orange": 150,
         "vegetables.v: broccoli": 40
       }
    } 

1. Can I keep the key name as is? What kind of dynamic mapping will help in doing this?
2. Is it possible to create dynamically fields like:

  {
      "stats": {
        "fruits": {
          "v": "apple",
          "count": 30
        }
      }
    }

Hi ab

Dot expander processor is what you are looking for https://www.elastic.co/guide/en/elasticsearch/reference/master/dot-expand-processor.html

It won't work with ":". If number of fruits / veggies are known then you can use rename processor.

Otherwise you will have to use script processor.
