SPEAKER: Rich Hickey, CTO Cognitect
TITLE: Datomic *
ABSTRACT:
Proponents of functional programming tout its many benefits, most of which are available only within a particular process, or afforded by a particular programming language feature. Anything outside of that is considered I/O, dangerous and difficult to reason about. But real systems almost always cross process and language boundaries, and most require, crucially, a very gnarly bit of shared state -- a database. In this talk we will examine how Datomic renders the database into that most prized and easy-to-reason-about construct, a value, and makes it available to multiple processes in multiple languages, functional and not. Along the way, we'll discuss the importance of immutability and time in representing information, the reification of process, and the mechanisms of durable persistent data structures.
