This js a good comprehensive overview of the Unified Analytics Framework (UAF) concept. Flow is a company that does what MH does but is cloud platform agnostic. I don't believe it's OSS (I prefer OSS) and I'm not sponsored or influenced by Flow to shill their stuff (I personally always go OSS as much as possible). Just wanted to share this feedback with the community, as analytics engines are evolving out of need to be far more than just analysis. https://m.youtube.com/watch?v=KgldM_qmsnw

As far as I understood, this is a Unified Analytics Framework: The Unified Analytics Framework (UAF) extends the Unified Namespace Structure (UNS) by allowing the connection of systems that do not fit the UNS as it has been defined. It translates the mismatched structure into the unified namespace structure, acting as a translation service for historical time series relational transactional data. The UAF operates as a broker for historical data transfer, allowing the passing of data through a broker-centric architecture and connecting systems that do not fit the UNS.
