elasticsearch - 无法使用动态模板映射在ouchdb上创建elasticsearch river

Question

当我尝试使用动态模板来指定映射时，将对象以外的所有内容都视为字符串，则River失败。

示例-我首先尝试为我的数据库清除所有先前的索引和河流-tempTest。

curl -XDELETE 'localhost:9200/_river/tempTest/'

curl -XDELETE 'localhost:9200/tempTest/'

curl -XPUT localhost:9200/tempTest -d '{
    "mappings": {
        "tempTest": {
            "dynamic_templates" : [
                {
                    "template_obj" : {
                        "match" : "*",
                        "match_mapping_type" : "object",
                        "mapping" : {
                            "type" : "object"
                        }
                    }
                },
                {
                    "template_str" : {
                        "match" : "*",
                        "mapping" : {
                            "type" : "string"
                        }
                    }
                }            
            ]
        }
    }
}'


curl -XPUT 'localhost:9200/_river/tempTest/_meta' -d '{
    "type" : "tempTest",
        "couchdb" : {
            "host" : "localhost",
            "port" : 5984,
            "db" : "tempTest",
            "filter" : null
            },
        "index" : {
            "index" : "tempTest",
            "type" : "tempTest",
            "bulk_size" : "100",
            "bulk_timeout" : "10ms"
            }
}'

完成此操作后，我在elasticsearch错误日志中得到以下错误日志。

河流类型必须为couchdb。试试这个:

curl -XPUT 'localhost:9200/_river/tempTest/_meta' -d '{
    "type": "couchdb",
    "couchdb": {
        "host": "localhost",
        "port": 5984,
        "db": "tempTest",
        "filter": null
    },
    "index": {
        "index": "tempTest",
        "type": "tempTest",
        "bulk_size": "100",
        "bulk_timeout": "10ms"
    }
}
