Question

I have an index with this settings and mappings.

  "number_of_replicas": 0,
  "analysis": {
    "analyzer": {}
    }

"mappings": {
  "properties": {
    "id": {
      "type": "keyword"
     },
    "title": {
      "type": "text"
    },
    "description": {
      "type": "text"
    },
    "manufacturer": {
      "type": "text",
      "fields": {
        "raw": {
          "type": "keyword"
        }
      }
    },
    "price": {
      "type": "scaled_float",
      "scaling_factor": 100
      }
    }
  }
}

This fields also exist in my file and i want to send my data from csv file to using .文件中，我想使用将我的数据从 csv 文件发送到 。
This is my logstash config file:

input {
  file {
    path => "E:\ElasticStack\Logstash\products.csv"
    start_position => "beginning"
    sincedb_path => "NULL"
   }
}
filter {
  csv {
      separator => ","
      columns => ["id","title","description","manufacturer","price"]
  }
}
output {
  elasticsearch {
     hosts => "http://localhost:9200"
     index => "amazon_products"
  }
  stdout {}
}

When if use this command The only message from logstash is:来自 logstash 的唯一消息是：
and it doesn't send data to elasticsearch并且它不向 elasticsearch 发送数据
Please Help Me. Thank You:)

Answer 1

Use forward slashes in your path configuration even on windows, also change the sincedb_path to NUL .

Try this config in your input

input {
  file {
    path => "E:/ElasticStack/Logstash/products.csv"
    start_position => "beginning"
    sincedb_path => "NUL"
   }
}

Answer 2

try to set the sincedb_path parameter to "NUL".
