java - 如何在elasticsearch中创建索引，以便每天上传数据时创建一个带有日期的新索引别名并允许我删除它们

Question

PUT myindex-000001
 {
  "aliases": {
  "myindex-alias":{
  "is_write_index": true 
   }
 }
}


 PUT _ilm/policy/my_policy
       {
         "policy": {
         "phases": {
         "hot": {
         "actions": {
          "rollover": {
           "max_size": "25GB" 
      }
    }
  },
  "delete": {
    "min_age": "180d",
    "actions": {
      "delete": {} 
    }
   }
  }
 }
}


PUT _template/my_template
    {
      "index_patterns": ["myindex-*"], 
      "settings": {
       "number_of_shards": 1,
       "number_of_replicas": 1,
        "index.lifecycle.name": "my_policy", 
        "index.lifecycle.rollover_alias": "myindex-alias" 
      }
    }

   POST myindex-000001
    {
     "settings": {
      "number_of_shards": 1,
        "number_of_replicas": 1,
           "index.lifecycle.name": "my_policy"
            }
          }

我尝试从java将数据加载到elasticsearch索引myindex-alias中。

我需要为每个新的上传日期提供单独的索引别名，例如 -

         myindex-000001
         myindex-000002
         myindex-000003 and so on.. 

所有内容都链接到一个策略，以便我可以根据需要删除任何别名。

他，策略非常相似，只需将 "max_age":"1d", 添加到您的负载中即可。查看更多here
