[QUESTION & DOCS]: hangar versus DVID?

[kurtsansom]

Executive Summary
how does the approach of hangar compare with DVID? I am looking at how solutions to managing really large datasets, and stored ML models. The project dvid seems like its doing something similar to hangar?

I don't know enough about devops to be able to determine what kind of solution I could or should choose or what one is buying into when they choose one.
