Datomic: Datalog, Databases, Persistent Data Structures With Rich Hickey
From this interview with Rich Hickey:
Q: So why don’t you like relational databases, why did you create a new system?
A: One of the objectives of a lot of new systems is to decentralize things in order to get greater scaling and have more flexibility. So there is actually a lot to like about traditional databases. I think relational algebra is a powerful tool , and I think transactions are powerful, so we want to retain transactions, we retain a relational-like model which we expose through a query language called Datalog, which has the same power as relational algebra. So we value those things quite a bit, but you want to move away from having one server or a cluster of servers do all the work, because it’s very difficult to scale that, and in an attempt to scale that, people are giving up some capabilities.
