Using "Not Grouped BY" when using Druid

[kasiviswanat...@gmail.com]

Hello,

We are evaluating Caravel with Druid as our backend. I have the following questions.

1. We have this option of "NOT GROUPED BY" during the slice creation. How is this used when we use Druid as the data source? I get this error when i select any column in this option. The error reads Choose either fields to [Group By] and [Metrics] or [Columns], not both

2. Is there an option to select all columns in the "Group By" ( Like a select * in the DB)

Thanks,

Kasi.
