_meta field
edit_meta field
editA mapping type can have custom meta data associated with it. These are not used at all by Elasticsearch, but can be used to store application-specific metadata, such as the class that a document belongs to:
resp = client.indices.create(
index="my-index-000001",
mappings={
"_meta": {
"class": "MyApp::User",
"version": {
"min": "1.0",
"max": "1.3"
}
}
},
)
print(resp)
response = client.indices.create(
index: 'my-index-000001',
body: {
mappings: {
_meta: {
class: 'MyApp::User',
version: {
min: '1.0',
max: '1.3'
}
}
}
}
)
puts response
const response = await client.indices.create({
index: "my-index-000001",
mappings: {
_meta: {
class: "MyApp::User",
version: {
min: "1.0",
max: "1.3",
},
},
},
});
console.log(response);
PUT my-index-000001
{
"mappings": {
"_meta": {
"class": "MyApp::User",
"version": {
"min": "1.0",
"max": "1.3"
}
}
}
}

The _meta field can be updated on an existing type using the
update mapping API:
resp = client.indices.put_mapping(
index="my-index-000001",
meta={
"class": "MyApp2::User3",
"version": {
"min": "1.3",
"max": "1.5"
}
},
)
print(resp)
response = client.indices.put_mapping(
index: 'my-index-000001',
body: {
_meta: {
class: 'MyApp2::User3',
version: {
min: '1.3',
max: '1.5'
}
}
}
)
puts response
const response = await client.indices.putMapping({
index: "my-index-000001",
_meta: {
class: "MyApp2::User3",
version: {
min: "1.3",
max: "1.5",
},
},
});
console.log(response);
PUT my-index-000001/_mapping
{
"_meta": {
"class": "MyApp2::User3",
"version": {
"min": "1.3",
"max": "1.5"
}
}
}
