How is the documentation for this deployment and tuning? Last time I checked I had the impression that anything about the dozen of different node types weren't very clear, not to mention details about the ingestion were all over the place.

And it was hard to find examples of configuration, ingestion other than basic tutorials

Docs definitely have rooms for improvement.

Architecturally, It is easier to visualize this two big group:

- query serving: coordinator, historical, broker

- ingestion: overlord, middlemanager

router unifies all of Druid API together.

I would start with the Helm chart to get some basic idea on tunings.
