What is this Druid-Grafana plugin?

Grafana doesn't supports Druid as a Data Source, this plugin aims to do so.

Features

At the time of writing, the plugin supports all Grafana features and all Druid queries:

• Druid queries: SQL, timeseries, topn, groupby, timeboundary, segmentmetadata, datasourcemetadata, scan, search, JSON
• Variables: Grafana global variables replacement, query variables, formatter druid:json (provide support for multi-value variables within rune queries).
• Alerts
• Explore
• Logs

if you're using a self-signed TLS certificate, an option to "Skip TLS verify" will be shown when "https" is used in datasource URI)
