Support for repeat options

[wonderino]

When repeat a panel, grafana-druid query does not split multiple variables.

For example, in the first SQL panel of Grafadruid Wikipedia Sample dashboard, I selected multiple cities as variables and chose the variable in Repeat by variable under Repeat options. Panels were automatically repeated, but the dataset did not.

I found that scopedVars is used when repeat a panel or row, it is passed to templateSrv replace method as local overrides. So I add scopedVars as arguments in DruidDataSource.applyTemplateVariables method and pass it to the replace method.

Thanks @wonderino !
How do I make this available in the plugin which I download via grafana? I am assuming that we have to release this? Is there a process to that? I'll be happy to help out.

Hello @Ghazanfar-CFLT,

Yep, we need to release to get it available on grafana.com.
I'll try to prepare a release soon (like in next days).

I've waited for this feature to be officially available. This is largely because I don't know how to build and install it by myself 😅

Released!

Now have to wait for Grafana.com to review & publish it, meanwhile:
