At the Spring S2G Forum in Munich, the Groovy project lead Guillaume Laforge elaborated on Groovy 1.7’s new and noteworthy improvements. There was a huge interest in Groovy at the forum, which reinforces our strategic investment in Groovy as a capable and mature JVM-based language.

Our team has developed a system for storing and processing huge amounts of log data using Hadoop. The challenge was to handle Gigabytes of log messages every day and enable querying the 30+ Terabyte archive with instantaneous results.

mgm develops several large scale web applications containing hundreds of forms, e.g. the e-government portal ElsterOnline Portal. Design, implementation, test, and maintenance of these forms implies significant effort. We are currently evaluating different technologies – including XForms, Wicket and JSF (ICEfaces) – that could help us to reduce these efforts, to improve quality and set the framework for our next generation web forms-centric applications.
