Hi, I have started using new Java client. I want to add new componentTemplate with mapping. What is the approach with the new client? This was the approach on 7.17: [java-rest-high-put-index-template-v2.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-put-index-template-v2.html) ---

Something like: ```auto client.cluster().putComponentTemplate(pct -> pct .name("my_component_template") .template(t -> t .settings(s -> s.numberOfShards("1").numberOfReplicas("0")) .mappings(m -> m .properties("foo", p -> p.text(tp -> tp)) ) ) ); ``` ---

Thanks for fast response. Is there an option to provide the mapping as JSON (like we had in v.7) ```auto Template template = new Template( null, new CompressedXContent(mapping), null); ComponentTemplate ct = new ComponentTemplate( template, version, null); ``` ---

This should do it. ```auto PutComponentTemplateResponse response = client.cluster().putComponentTemplate(pct -> pct .name("my_component_template") .template(t -> t .withJson(new StringReader("{\n" + " \"mappings\": {\n" + " \"properties\": {\n" + " \"@timestamp\": {\n" + " \"type\": \"date\"\n" + " }\n" + " }\n" + " }\n" + " }")) ) ); ``` ---

Is there any docs page for new client? Like you had in v.7: [java-rest-high-put-index-template-v2](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-put-index-template-v2.html) ---

Sadly no. But you have some advices from the doc: [API conventions | Elasticsearch Java API Client [8.13] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/api-conventions.html) And my blog post: [Switching from the Java High Level Rest Client to the new Java API Client | Elastic Blog](https://www.elastic.co/blog/switching-from-the-java-high-level-rest-client-to-the-new-java-api-client) And my "demo" repo: > ---

Can you also show how to create index template with settings, alias and componentTemplate? Like: [put-index-template](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-put-index-template-v2.html#_settings_2) ---

Should be straightforward: ```auto client.cluster().putComponentTemplate(pct -> pct .name("my_component_template") .template(t -> t .settings(s -> s.numberOfShards("1").numberOfReplicas("0")) .mappings(m -> m .properties("foo", p -> p.text(tp -> tp)) ) ) ); PutIndexTemplateResponse response = client.indices().putIndexTemplate(pit -> pit .name("my_index_template") .indexPatterns("my-index-*") .composedOf("my_component_template") .template(t -> t .aliases("foo", a -> a .indexRouting("bar") ) .settings(s -> s.numberOfShards("1").numberOfReplicas("0")) .mappings(m -> m .properties("foo", p -> p.text(tp -> tp)) ) ) ); ``` ---
