I've defined a custom car with base=vanilla. I'm trying to set multiple data paths using data\_paths, but I'm not sure how to make rally recognize the value.

I've tried

```
/path/0,/path/1
/path/0/,/path/1/
/path/0, /path/1
/path/0","/path/1
/path/0','/path/1

```

In the first three cases, it treats the paths as a single string and I end up with

```
path.data: ['/path/0,/path/1']
path.data: ['/path/0/,/path/1/']
path.data: ['/path/0, /path/1']

```

in my elasticsearch.yml. In the ones where I explicitly add quotes, the end result uses the opposite quote type to make them a single string. So

```
/path/0","/path/1

```

becomes

```
path.data: ['/path/0","/path/1']

```

and

```
/path/0','/path/1

```

becomes

```
path.data: ["/path/0','/path/1"]

```

How can i delimit my strings so that elasticsearch will store in multiple locations?

Hello,

Did you try to specify `data_paths` via a json file, as described [here](https://github.com/elastic/rally-teams/tree/master/cars/v1/vanilla#parameters) and use an array e.g.:

```auto
{
    "data_paths": ["/mnt/disk1", "/mnt/disk2"]
}

```

store it as `car_params.json` and then reference it using `car_params=/path/to/car_params.json`?

I ended up just changing the elasticsearch.yml file in vanilla to match what I wanted, but thank you for the recommendation!
