Best practices around database/retention policy/measurement design

@andyfeller Ideally you have a standard set of fields/tags within the same measurement. That, as you astutely point out, means that you can have data that is orthogonal in the same measurement. This is not recommended and is not a performant way to store data. There are use cases where this can be advantageous and, because we are a columnar store, performant (this post is a good example).
