I want to parse field with spacial format (like Json) with using elasticsearch without logstash , is that possible with using elasticsearch analyze?

If it's possible,where can i start?  
Or there is another way?

example :  
before parse

{ 'timestamp' : 2020-12-9,  
'message' : {'a':3,'b':4}  
}

after :  
{'timestampe' :2020-12-9,  
message :{'a':3,'b':4}  
'a' : 3,  
'b' : 4,}

thank you!

Welcome!

You can use the [ingest pipeline feature](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/ingest.html).

For example, based on this documentation:

> **[Set processor | Elasticsearch Reference \[7.10\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/set-processor.html)**

You can write

```auto
PUT _ingest/pipeline/extract_message
{
  "processors": [
    {
      "set": {
        "field": "a",
        "value": "{{message.a}}"
      }
    },
    {
      "set": {
        "field": "b",
        "value": "{{message.b}}"
      }
    }
  ]
}

PUT index/_doc/1?pipeline=extract_message
{
  "message": {
    "a":3,
    "b":4
  }
}
GET index/_doc/1

```

That should work.
