Use Case

My document is an object of objects

{
  "attrs": {
	  "useless_key": "jibber_jabber",
 
    "batch": {
      "created_at": 1605443039,
      "id": "batch_1213"
    },
    
    "session": {
      "created_at": 1605443039,
      "tags": ["affiliate_1", "checkout"]
    }
  }
}

with potentially lots of currently unknown attrs.* sub-objects.

I want to map all attrs.*.created_at fields as timestamps and the rest (attrs.*.*) as keywords.

At the same time, I want to set index: false on everything else inside attrs to not make it searchable.

Approach

Let's use dynamic_templates with path_match and path_unmatch.
