Rich Hickey explains the basics of Datomic, its approach to transactions and query, Datalog, CAP, ACID and BASE, and much more.
Stuart Halloway explains Datomic, programming transactional behavior with Datomic, Datalog and logic programming, programming with values, Clojure Reducers and much more.
Rich Hickey and Justin Sheehy talk about scalability and transactionability of datastores. They explain tradeoffs for achieving read and/or write scalability on top of Datomic and Riak.
Rich Hickey explains the ideas behind the Datomic database: why Datalog is used as the query language, the functional programming concepts at its core, the role of time in the DB and much more.
Jonas Bonér explains the Akka project and the types of actors it offers as well as its transactional features. Also: a preview of how Akka 2.0 changes the management of (remote) actors.
In this interview, recorded at QCon London, Google architect Gregor Hohpe talks to Stefan Tilkov about his new work on conversation patterns. Building upon his earlier work on enterprise integration patterns, Gregor sees conversation patterns as playing a critical role in real-world interactions, with analogies in the natural world.
Eric Evans, the author of Domain Driven Design, interviews Greg Young about the architecture implemented for a system processing tens of thousands of transactions per second. It's not just the sheer number of transactions that is challenging, but the time constraints imposed are those specific to real-time systems. Greg reveals some of the architecture elements of the system's design.
In this interview, recorded at QCon London 2008, Red Hat Director of Standards and Technical Development Manager for the SOA platform Mark Little talks about extended transaction models, the history of transaction standardization, their role for web services and loosely coupled systems, and the possibility of an end to the Web services vs. REST debate.
In this interview from QCon San Francisco 2007, Randy Shoup discusses the architecture of eBay. Topics discussed include eBay's architectural principles, horizontal and vertical partitioning, ACID vs. BASE, handling data inconsistency, distributed caching, updating eBay on the fly, architectural and coding standards, eBay's search infrastructure, grid computing, and SOA.
Dan Pritchett gives us an inside look into the decisions behind on of the largest scale architectures in the world: eBay. In explaining how the scale of eBay turns simple requirements a complex engineering problem, he walks us through the technical and organizational challenges of managing eBay's architecture.
Spring core developers Rob Harrob and Juergen Hoeller talk about what, why, and how of the new features in Spring 2, including XML configuration, custom tags, AspectJ integration, and migrationg to Spring 2.
