How to write integration tests depending on Druid?

I am coding an application that generates reports from a Druid database. My integration tests need to read data from that database.

My current approach involves creating synthetic data for each of the tests. However, I am unable to remove data created from the database (be it by removing entries or completely dropping the schema) as described here.

I think that either I am completely wrong with my approach or there is a way to delete information from the database that I haven't been able to find.
