Defines one mapping type for a set of of subfields

Elastic Stack Elasticsearch
1

Hello,

Is there a way to define a type for a set of sub fields ? Let say I have:
myfield.mysubfield1
myfield.mysubfield2

Is it possible to define the mapping like that :

  "myfield": {
    "type": "float",
  },

So as mysubfield1 and mysubfield2 will be of type float without having to define all of them in the mapping ?

Thanks

You can do something like this with dynamic templates : https://www.elastic.co/guide/en/elasticsearch/reference/6.1/dynamic-templates.html

Thanks @dadoonet for the answer, from this dynamic template how could I map an array of repeated set of fields of same type ? and without the same type (not sure it's possible from the documentation) ? :

Example :
"field":{"subfield1":[{"subsubfield1":"1","subsubfield2":"246","subsubfield3":"6538","subsubfield4":"-84","subsubfield5":"102"},{"subsubfield1":"1","subsubfield2":"246","subsubfield3":"6540","subsubfield4":"-92","subsubfield5":"102"}]

Please format your code using </> icon as explained in this guide and not the citation button. It will make your post more readable.

Or use markdown style like:

```

Please edit your post.

In the example you posted, what are the expected settings/mappings you would like to have?

Sorry, post updated. I think the output would looks like a concatenation of the values for each identical subfields :

field.subfield1.subsubfield1=[1, 1]
field.subfield1.subsubfield2=[246, 246]
field.subfield1.subsubfield3=[6538, 6540]
field.subfield1.subsubfield4=[-84, -92]
field.subfield1.subsubfield5=[102, 102]

I don't see why dynamic template would not work in that case.
Did you try?

I tried, but in fact I mixed some stuff and when checking again there is no error for parsing this kind of data except that it leave them as a json displayed in Kibana with a warning saying that "Objects in array are not well supported" :

 {
  "subsubfield1": "131",
  "subsubfield2": "246",
  "subsubfield3": "1",
  "subsubfield4": "9226",
  "subsubfield5": "-75"
},
{
  "subsubfield1": "171",
  "subsubfield2": "246",
  "subsubfield3": "10",
  "subsubfield4": "9227",
  "subsubfield5": "-83"
},
{
  "subsubfield1": "134",
  "subsubfield2": "245",
  "subsubfield3": "3",
  "subsubfield4": "9420",
  "subsubfield5": "-91"
},
{
  "subsubfield1": "121",
  "subsubfield2": "249",
  "subsubfield3": "1",
  "subsubfield4": "9404",
  "subsubfield5": "-95"
}

Could you provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.
