Here at Sumo Logic we write a lot of Scala code. We also have a lot of data, so some of our code has to go really, really fast. While Scala allows us to write correct, clear code quickly, it can be challenging to ensure that you are getting the best performance possible.
This article explores some of Java 8’s new features, using both Java’s proposed syntax and Scala. We cover lambda expressions, higher-order functions, parallel collections and virtual extension methods aka traits. Besides this, we will provide insights into the new paradigms integrated in Java 8, such as functional programming.
Spark is a fast, in-memory cluster computing framework with a language-integrated interface in Scala. It shines at iterative MapReduce (e.g. machine learning) and interactive data mining, where keeping data in memory provides substantial speedups.
He CC'ed Martin Odersky, the lead designer of Scala and Typesafe’s Chief Architect. Given that the two people best-situated to improve Scala had just asked me about my experience over the past two years of using Scala, I wrote a long, considered, brutally honest response.
Typesafe provides an easy-to-use packaging of the Scala programming language, Akka middleware, and developer tools via the open source Typesafe Stack, as well as commercial support and maintenance via the Typesafe Subscription. Typesafe also provides training and consulting services to accelerate the commercial adoption of Scala and Akka.
The Manifests. A Manifest is class whose instances are objects representing types. Since these instances are objects, you can pass them around, store them, and generally call methods on them. With the support of implicit parameters, it becomes a very powerful tool
Citing a need to be able to respond faster to events, and disappointment in the feature set and timeframe for Java 7, the team behind guardian.co.uk is using Scala as an alternative to Java for their new projects. InfoQ spoke to Web Platform Development Team Lead Graham Tackley about their current stack, the reasons behind the move, and the experience of using Scala in large-scale development.
