The conf file is below:

input{

file{  
path =\>"S:\ELK\data\studymig.csv"  
start\_position =\> "beginning"  
sincedb\_path =\> "\dev\null"  
}

```
}

```

filter {  
csv {  
separator =\>","  
columns =\>["a","b","c","d","e"]  
}

}  
output {  
elasticsearch {  
hosts=\>"localhost"  
index =\>"studymig"  
document\_type =\>"study\_status"  
}  
stdout {  
codec =\> rubydebug  
}  
}

If you are running on Windows and you want to suppress the use of a persistent sincedb then set

```
sincedb_path => "NUL"

```

not /dev/null.
