The website does a terrible job of communicating what they are. Had to click to the docs to kind of get a quick summary.

In the context of their business I guess this writeup makes sense, it is afterall a marketing piece for their service. I don't agree with it though. I get the simplicity of running everything in a single db stack but I don't think any of the tools they listed were really going to be required to build something like this into another data warehouse.
