Ad hoc filters not supported

[Davonex]

Hello

When i create a new variable of "Ah hoc Filters" type and i choice a Druid data source,

I receive this error message : This data source does not support ad hoc filters yet.

Have you planned to do support the "ad hoc filters" ?

Thank you

Hello @Davonex
Ad hoc filters are a bit obscure to me yet (see https://community.grafana.com/t/ad-hoc-filters-for-a-custom-plugin/1867 ).
I'd love the plugin to get such feature support, if you're willing to write the code for it, I'd be happy to provide you some active support :) If not, then I dunno when this feature will come.

Hey @jbguerraz I've started working on this issue on the behalf of my employer (Lolo Company - https://www.lolo.co), and I've got it to work fairly well for SQL based queries. I'd very much like your opinion on my proposed solution: master...lolocompany:druid-grafana:master
If you think that simply SQL support is enough to warrant a PR, then I'll open one next week. Otherwise I'd very much like your help in figuring out how to add adhoc support for the remaining query types.
