I am a big SQL fan but not all data has to be relational.

Let’s say I want the GPS coordinates of ten million vehicles every 5 seconds. I have a vehicle id, a timestamp, and coordinates. I do not care if a few writes get lost. Why does this have to be relational?

And perhaps I also record other info that may change from vehicle to vehicle. Perhaps just values that are true if present. DoorOpen, BrakeApplied, LightsOn, LightBarOn, EngineOn, etc. I may only be displaying this data in a UI. I may get different values from every vehicle or even every write. There is no “schema”. I mean, I can have a JSON field or something in my relational table? But this is not exactly relational anymore.
