		columns => ["name","uid","startdate","enddate"]

	}
	mutate {convert =>[uid , "integer"]}
	
	  date {
      match => ["startdate", "ISO8601", "YYYY/MM/dd HH:mm:ss","YYYY/MM/dd HH:mm"]
      target => "startdate"
      locale => "en"
	  timezone => "Asia/Dubai"
    }
	
	  date {
      match => ["enddate", "ISO8601", "YYYY/MM/dd HH:mm","YYYY/MM/dd HH:mm:s"]
      target => "enddate"
      locale => "en"
	  timezone => "Asia/Dubai"
    }
	  mutate {
    add_field => {
      "index_name" => "%{[@metadata][s3][key]}"
    }
   
  }

  }

Assuming that the S3 path is available in a field in the event you can use a grok filter to extract the name. How to extract a filename from a full path has been asked several times before so you should be able to find examples in the archives.
