elasticsearch Windows操作系统中的sincedb_路径

我在学麋鹿。我读了教程。本教程使用Linux操作系统，而我使用的是Windows操作系统

来自教程

input {
  file {
    path => "/home/zenitk/hackernews.csv"
    start_position => "beginning"
    sincedb_path => "/dev/null"
  }
}

filter {

    csv {
        columns => [
            "id","by","score","time","time_ts","title",
            "url","text","deleted","dead","descendants","author"
        ]
        separator => ","
        skip_header => true
    }

    date {
        match => ["time_ts", "yyyy-MM-dd HH:mm:ss z"]
        target => "post_date"
        remove_field => "time_ts"
    }

    mutate {        
        rename => { 
            "dead" => "is_dead"
            "id" => "[@metadata][id]"            
        }
        
        convert => {
            "is_dead" => "boolean"
        }
       
        remove_field => [
            "@timestamp", 
            "host",
            "message", 
            "@version", 
            "path", 
            "descendants",
            "time"
            "id"
        ]
    }
}

output {

  elasticsearch { 
      hosts => ["localhost:9200"]
      index => "hackernews_import"
      document_id => "%{[@metadata][id]}"
  }

  stdout {}
}

在Windows操作系统中，与

sincedb\u path=>“/dev/null”

等效的是什么？

Windows等效的是

sincedb_path => "NUL"

三个字母，大写。这将防止内存中的sincedb在重新启动时被持久化。始终使用内存中的sincedb
