Logstash / ElasticSearch-如何处理父母/子女关系

Question

I have added a mapping in my elastic search index in order to have a child for my documents:

PUT /test/_mapping/goals
{
  "goals": {
        "_all": {
           "enabled": false
        },
        "_parent": {
           "type": "myparentdoc"
        },
        "_routing": {
           "required": true,
           "path": "_id"
        },
        "properties": {
           "goals": {
              "type": "long",
              "null_value": 0
           }
        }
     }
  }

Now I would like to import the corresponding documents with logstash.

How can I configure my logstash in order to give the parent id information.

I tried to configure action parameter in elasticsearch output configuration without any success (based on elasticsearch documentation for bulk processing of children docs).

To summarize, how should I put _parent information?

Any idea?

Thanks

Finally I had just to add _parent information:

filter{
   mutate{
     add_field => { "_parent" => "%{_parentId}" }
   }

}
