Disabling dynamic mapping

Elastic Stack Elasticsearch
1

i wanted to disable dynamic mapping for my indices.. but it is somehow not
working for me.. i looked at the documentation and im still getting
confused.. tried couple of things and it didnt work.

does anyone have a working example?

e.g., i tried the below and that didnt work -
{ "number_of_shards" : 2,
"mapper.dynamic" : false
}

i looked at this link -
http://www.elasticsearch.org/guide/reference/mapping/object-type.html

it doesnt really tell how to disable at root level.

thanks

Hello,

Here's a gist that you can adapt for a specific index:

If you need to do this globally, you can add this line to your
elasticsearch.yml:
index.mapper.dynamic: false

Restart Elasticsearch, and it should work for all new indices.
Alternatively, you should be able to do it with a template that matches all
indices, or the index names your interested in.

Best regards,
Radu

Hello,

if you want to disable the dynamic mapping on the root level of your object
as you asked for and not on the complete index as Radu mentioned you can do
it in the following way:

https://gist.github.com/mkleen/4942355b8af22daa4a4e

This will not prevent that an object gets created with unmapped fields, but
it wont create a dynamic field in the index as shown above in the example.

Regards,

Michael

How about if I want an error raised if I try to index a field that's not
defined as a part of the mapping?

Thanks.

In this case, you can specify dynamic: "strict". Any attempt to index an
unmapped field will cause the op to fail.

In the yaml config file? Or is it a part of an index's mapping? Can you
give an example of how to use that setting?

Thanks for the info.

You can use it when you specify the mapping, eg at index creation time:

curl -XPUT 'http://127.0.0.1:9200/test/?pretty=1' -d '
{
"mappings" : {
"mytype" : {
"dynamic" : "strict",
"properties" : {
"foo" : {
"type" : "string"
}
}
}
}
}
'

You can also set it for all types in an index by specifying the default
mapping:

curl -XPUT 'http://127.0.0.1:9200/test/?pretty=1' -d '
{
"mappings" : {
"default" : {
"dynamic" : "strict"
}
}
}
'

clint

If I want to specify my own mapping for some fields yet would like the
dynamic mapper to pick up on fields that I haven't specified, is this
possible?

Yes, just put the mapping with the fields you want to specify, and leave
it as the default of dynamic: true. Then any new fields will by
dynamically detected and added
