Jamie Allen describes three patterns using Akka actors: handling a lack of guaranteed delivery, distributing tasks to worker actors and implementing distributed workers in an Akka cluster.
Nat Pryce, Steve Freeman advise on design principles useful to create code structures with objects that fit together and communicate, and where the capabilities and the information flow are explicit.
Sean Owen provides examples of operational analytics projects, presenting a reference architecture and algorithm design choices for a successful implementation based on his experience Oryx/Cloudera.
Sander Hoogendoorn shares patterns to avoid framework issues by using layered architectures, bridge patterns, managers-providers, DI, descriptors and layer super-types, including code samples.
Venkat Subramaniam shows how to implement several design patterns, including some GoF ones, using Groovy’s dynamic nature and closures.
