Thanks for this post! Naive question: why not "just use Great Expectations"? At first blush GE seems like it has a lot of what you need out of the box: checks definable in YAML, extensibility, and connectors to many major data sources.
Was there something you all found lacking there which made "roll your own" the right approach here?
