Elastic 5.6 dynamic template mappings _default_

gabriel_tessier · September 19, 2017, 8:30am

Hi,

I'm little confused with the mapping deprecation, I read here:

https://www.elastic.co/guide/en/elasticsearch/reference/6.x/default-mapping.html

I'm creating a new app using the last 5.6 elastic and I have dynamic template mapping defined like in logstash here:

elastic/logstash/blob/master/modules/netflow/configuration/elasticsearch/netflow.json

{
    "order": 0,
    "template": "netflow-*",
    "mappings": {
        "_default_": {
            "_meta": {
                "version": "7.0.0"
            },
            "dynamic_templates": [
                {
                    "application_id": {
                        "path_match": "netflow.application_id",
                        "mapping": {
                            "type": "integer"
                        }
                    }
                },
                {
                    "bgp_ipv4_next_hop": {
                        "path_match": "netflow.bgp_ipv4_next_hop",

According to the documentation "default" is deprecated in 6.0 so If I use it in 5.6 I'll have deprecation warning when I'll upgrade!
I prefer to go the correct way now, so I have nothing to do later. But the problem is I don't find in the doc what to use to have the equivalent? What is the correct way to go?

Thanks for any help.

Instead of using _default_, use the actual type that you are passing in.

Thanks for the reply, now I get it but my case was not exactly this, sorry for the confusion.

"template": "*", <---- I have a top template that will apply to all my indices...

Or does it mean that all my type will be named "unamed" <--- or whatever generic name?

Ok I got it!!! anyway it make sense in a way that it will be removed so don't care about the name!

It took time but now I got it!

Thanks a lot!
