Ask HN: State of Art of MultiVersion Concurrency Control

Sometime ago I dived into (graph) database I learned about MVCC. This is very interesting topic used in many databases but I find that it lakes engineer documentation. - What do you know about MVCC? - What you would like to know? Also there is a new academic formalization of MVCC (less than 10 year old) through a paper that I lost, do you know where I can find it?
