My company needs Druid for interactive analytics.
With all the query libraries available as listed (http://druid.io/docs/latest/development/libraries.html), why is there no java client library? Java is very popular.
I need the client library to issue nested groupBys or iterated topNs. I don’t wanna reinvent the wheel of the logic to create the json query string especially in a nested form.
Does anyone know why?
