Have a document like this:
```auto
{
"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:
```auto
{
"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](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.
