Elasticsearch 5：禁止动态增加字段


#Elasticsearch 笔记

在 _mapping 中指定dynamic 为 strict 即可。

示例：

# 步骤1: 创建索引
PUT school

# 步骤2: 创建 type
POST school/student/_mapping
{
  "dynamic": "strict",
  "properties" : {
    "name" : {
      "type" : "keyword"
    }
  }
}

执行下面的 DSL 会成功：

PUT school/student/1
{ "name": "letian" }

但下面的DSL 会失败：

PUT school/student/2
{ "name": "letian", "age": 20 }

报错信息如下：

{
  "error": {
    "root_cause": [
      {
        "type": "strict_dynamic_mapping_exception",
        "reason": "mapping set to strict, dynamic introduction of [age] within [student] is not allowed"
      }
    ],
    "type": "strict_dynamic_mapping_exception",
    "reason": "mapping set to strict, dynamic introduction of [age] within [student] is not allowed"
  },
  "status": 400
}
