【问题描述】:
我在我的项目中使用 Java 高级别的休息客户端,我想根据文档数量限制我的索引。我正在使用翻转 api,但它不会自动创建索引。 下面会给出代码。
我正在创建索引模式,以便我的自定义分析器将应用于遵循相应模式的所有其他索引。
PutIndexTemplateRequest request = new PutIndexTemplateRequest("testingtemplate");
request.source("{\n" +
" \"index_patterns\":[\n" +
" \"test_log-*\"\n" +
" ],\n" +
" \"settings\": {\n" +
" \"analysis\": {\n" +
" \"analyzer\": { \n" +
" \"my_analyzer\": {\n" +
" \"type\": \"custom\",\n" +
" \"tokenizer\": \"whitespace\",\n" +
" \"filter\": []\n" +
" }\n" +
" }\n" +
" }\n" +
" },\n" +
" \"mappings\": {\n" +
" \"properties\": {\n" +
" \"fullLog\": {\n" +
" \"type\": \"text\",\n" +
" \"analyzer\": \"my_analyzer\"\n" +
" }\n" +
" }\n" +
" }\n" +
" }",XContentType.JSON);
return client.indices().putTemplate(request,RequestOptions.DEFAULT).isAcknowledged();
我的翻转码。在这里,我想在索引获取一个或文档时翻转一个。
final RestHighLevelClient client = new RestHighLevelClient(
RestClient.builder(new HttpHost("localhost", 9200, "http")));
boolean isIndexTemplateCreated = createIndexTemplate(client);
System.out.println(isIndexTemplateCreated);
CreateIndexRequest request = new CreateIndexRequest("test_log-1");
request.alias(new Alias("temp_alias_new"));
CreateIndexResponse createIndexResponse = client.indices().create(request, RequestOptions.DEFAULT);
RolloverRequest roll_req = new RolloverRequest("temp_alias_new",null);
roll_req.addMaxIndexAgeCondition(new TimeValue(7, TimeUnit.DAYS));
roll_req.addMaxIndexDocsCondition(1);
roll_req.addMaxIndexSizeCondition(new ByteSizeValue(5, ByteSizeUnit.GB));
RolloverResponse rolloverResponse = client.indices().rollover(roll_req, RequestOptions.DEFAULT);
Map<String,Object> map = new HashMap<>();
map.put("fullLog","Hi");
client.index(new IndexRequest("temp_alias_new").source(map), RequestOptions.DEFAULT);
map.put("fullLog","hello");
client.index(new IndexRequest("temp_alias_new").source(map), RequestOptions.DEFAULT);
但是代码不工作并且翻转 api 没有自动创建索引。所有 2 个文档仅存储在 test_log-1 索引中。 我的代码有错误吗?
谢谢
