For uninitiated, Nikita has created in-memory database with mostly compatible API (datalog) for ClojureScript or Javascript. My impression is that his variant actually has more wide-spread use than original Datomic, based on number of open source projects that use each. I used DataScript for a while to get familiar with graph database querying. I was fascinated how easy it is to construct queries that mine obscure relations between distantly related entities. I hope I get to use similar tech again.
