1. Is the _‘ **backend plugin** ’_ mandatory in order to communicate with the server from which the data is fetched ?  
-or- can any code be executed in the `query` method in _DataSource.ts_ ?

2. Must the backend plugin be written in **GO**?

3. Following the example in:  
[https://github.com/marcusolsson/grafana-csv-datasource/blob/master/docs/adding-datasource-backend.md](https://github.com/marcusolsson/grafana-csv-datasource/blob/master/docs/adding-datasource-backend.md) - Grafana server fails to init the plugin:

=\>

> C:\Grafana\grafana-6.4.0-beta1\data\plugins\csv-datasource\dist/csv-  
> datasource\_windows\_amd64.exe": file does not exist

The exe file does exist no disk, but I am on Windows so it seems the separating character should be changed. What file is responsible for that ? **where should I change ?**

1. You don’t need a backend plugin to write a data source. The data source plugin can communicate directly with your database.

2. For now, we only support Go

3. I’m not sure we’re this is defined. I’ll see if I can look it up!
