Do you understand that he is talking about Lacinia, which is from WalMart? Do you feel that WalMart is esoteric? Do you wonder why WalMart has decided to commit to Clojure? A friend of mine offers the somewhat humorous summary of Clojure as "a library that makes concurrency easier in Java." And I suspect that is why so many large companies are moving towards it. These were companies that had a large number of Java programmers. Presumably the programmers often made mistakes regarding concurrency, and they were looking for a way to make it easier to manage concurrency. And so they switched to Clojure. Interop between Java and Clojure is seemless, so a lot of companies that are already using Java can add in Clojure painlessly. Actually, I should state that more strongly, Clojure removes some of the pain of dealing with concurrency. Lacinia is new. The first public release was just 6 months ago: https://github.com/walmartlabs/lacinia/commits/master?after=14c340a16b82de6ed3d0651b9de7d08c7651e447+419 https://github.com/walmartlabs/lacinia/commits/master?after=... The fact that big companies like WalMart are committing to Clojure, and then releasing their libraries to the community, suggests that Clojure is going mainstream.
