Mapping _id field from the fields specified

Let say i have a document with id field inside. When I submit the document to an index without id, it will generate id automatically.

Is there any possibility that it should take the inside id or any internal document field as _id ?


That can only be done using Ingest Node features. For instance, here is a Set Processor configuration that would read value for internal id and set it as document's id:

  "set" : {
    "field" : "_id",
    "value" : "{{id}}"
