How does Druid compare to Exasol?

Hi guys,

I am currently testing Exasol to power our analytics requirements - complex data more than big data, with about 400 users, so more BI than data science.

I am really happy with Exasol, but I was wondering if Druid.io compares in any way?

I know the solutions are quite different actually (Exasol is in memory, Druid is not, etc.). But in terms of a “fast data storage” place where I can push my data and connect BI tools like Tableau/PowerBI, how does Druid work?
