@estliberitas hello, your project is great. And I have a similar problem. I wanted to add a **DistinctCount aggregator**, but the framework didn't provide a similar interface. [http://druid.io/docs/0.12.0/development/extensions-contrib/distinctcount.html](http://druid.io/docs/0.12.0/development/extensions-contrib/distinctcount.html)
Can I use dimensions() in **topN**?
