I miss a piece of info here, could someone please fill in? Rich Hickey is known for Clojure, Metadata Partners for Datomic. What are the Relevance guys known for?<p>(Honest question, not a cheap attempt at dismissal :-) )
I attended a tech conference earlier this year where Rich Hickey was speaking. He was trumpeting the fact that data never really gets deleted in Datomic, and someone brought up the question: What happens if you are legally required to delete something from your database? I seem to remember him saying that Datomic wasn't really designed for that scenario, which sounds like a major problem.
