模拟多组件模板
编辑模拟多组件模板
编辑由于模板不仅可以由多个组件模板组成，还可以由索引模板本身组成，因此有两个模拟 API 用于确定生成的索引设置是什么。
模拟将应用于特定索引名称的设置
resp = client.indices.simulate_index_template(
name="my-index-000001",
)
print(resp)
const response = await client.indices.simulateIndexTemplate({
name: "my-index-000001",
});
console.log(response);
POST /_index_template/_simulate_index/my-index-000001
模拟将从现有模板应用的设置
resp = client.indices.simulate_template(
name="template_1",
)
print(resp)
const response = await client.indices.simulateTemplate({
name: "template_1",
});
console.log(response);
POST /_index_template/_simulate/template_1
您也可以在模拟请求中指定模板定义。这使您能够在添加新模板之前验证设置是否按预期应用。
resp = client.cluster.put_component_template(
name="ct1",
template={
"settings": {
"index.number_of_shards": 2
}
},
)
print(resp)
resp1 = client.cluster.put_component_template(
name="ct2",
template={
"settings": {
"index.number_of_replicas": 0
},
"mappings": {
"properties": {
"@timestamp": {
"type": "date"
}
}
}
},
)
print(resp1)
resp2 = client.indices.simulate_template(
index_patterns=[
"my*"
],
template={
"settings": {
"index.number_of_shards": 3
}
},
composed_of=[
"ct1",
"ct2"
],
)
print(resp2)
response = client.cluster.put_component_template(
name: 'ct1',
body: {
template: {
settings: {
'index.number_of_shards' => 2
}
}
}
)
puts response
response = client.cluster.put_component_template(
name: 'ct2',
body: {
template: {
settings: {
'index.number_of_replicas' => 0
},
mappings: {
properties: {
"@timestamp": {
type: 'date'
}
}
}
}
}
)
puts response
response = client.indices.simulate_template(
body: {
index_patterns: [
'my*'
],
template: {
settings: {
'index.number_of_shards' => 3
}
},
composed_of: [

]
}
)
puts response
const response = await client.cluster.putComponentTemplate({
name: "ct1",
template: {

"index.number_of_shards": 2,
},
},
});
console.log(response);
const response1 = await client.cluster.putComponentTemplate({
name: "ct2",
template: {
settings: {
"index.number_of_replicas": 0,
},
mappings: {
properties: {
"@timestamp": {
type: "date",
},
},
},
},
});
console.log(response1);
const response2 = await client.indices.simulateTemplate({
index_patterns: ["my*"],
template: {
settings: {
"index.number_of_shards": 3,
},
},
composed_of: ["ct1", "ct2"],
});
console.log(response2);
PUT /_component_template/ct1
{
"template": {
"settings": {
"index.number_of_shards": 2
}
}
}
PUT /_component_template/ct2
{
"template": {
"settings": {
"index.number_of_replicas": 0
},
"mappings": {
"properties": {
"@timestamp": {
"type": "date"
}
}
}
}
}
POST /_index_template/_simulate
{
"index_patterns": ["my*"],
"template": {
"settings" : {
"index.number_of_shards" : 3
}
},
"composed_of": ["ct1", "ct2"]
}
响应显示将应用于匹配索引的设置、映射和别名，以及其配置将被模拟模板体或更高优先级模板取代的任何重叠模板。
