More Groovy Track

Slides: http://www.slideshare.net/SpringCentral/groovy-android-41263570

For 10 years, Groovy has dramatically improved the productivity of Java developers on the desktop. With unique like closures, builders, AST transformations, traits, optional static compilation and many more, Groovy turned out to be a very competitive language on the JVM. Compared to other JVM languages, Groovy has the major advantage of being totally Java-friendly, both in terms of syntax and interperability. But during those years, what happened on the mobile world? In particular, Android developers are used to develop applications in Java, so why Groovy, a JVM language, wouldn't be usable for Android development too? Can we ease the pain of Android developers too?

Essential Grails Track

Slides: http://www.slideshare.net/SpringCentral/experiences-using-grails-in-a-microservice-architecture-spring-one2gx2014-41177964

For some web applications it does not make sense to have 1 monolithing process which handles all of the requirements of the application. More and more often Grails is showing up in microservice architectures where instead of building 1 monolithing web application which is responsible for all of the pieces of the application puzzle, microservice applications are being assembled which collectively solve the requirements of the larger application. Grails is very well suited for this type of architecture. A microservice based architecture can result in applications which are easier to build, easier to test, easier to extend and are easier to adapt to changing business requirements.

What is the role of asynchronous, non-blocking style-communication in microservices? Join Stephane Maldini for a revealing look at why reactive components are so important in an eventually-consistent approach like microservice architecture. When services own their data and are completely independent, having a (reactive) abstraction layer can perform a variety of roles. Being able to parallelize resources a microservice owns is an important technique. Another might be as an event bus, pulling state data from various micro services dynamically, checking against the cached, fairly up-to-date local copy. While a microservice has “all” the data it needs from other services to respond to a request, this data is not necessarily up-to-date—an important constraint to be prepared to accept. Stephane will also discuss other async use cases outside of microservices and how www.reactive-streams.org protocol support allows levels of portability across vendor implementations.

Big Data Track

Spring XD aims to provide a one stop shop for writing and deploying Big Data Applications. It provides a scalable, fault tolerant, distributed runtime for Data Ingestion, Analytics, and Workflow Orchestration using a single programming, configuration and extensibility model. By not requiring developers to rationalize all of this themselves across the many different solutions available today, Spring XD greatly reduces the inherent complexity of Big Data development. It's all built on proven projects like Spring Integration, and Spring Batch. You'll see for yourself how this heritage combines to provide a scalable runtime environment, that is easily configured and assembled via a simple DSL.

Big Data Track

As Hadoop goes mainstream in enterprise big data deployments, IT organizations expect and demand enhanced operational management of their Hadoop clusters in production. Admins require more than just cluster health monitoring; they need the ability to do real time workload analysis for performance tuning and troubleshooting. Real-time log analysis of jobs at a user or application level can allow admins to manage and tune workloads better, especially in multi-tenancy Hadoop cluster services. Join us to learn how Pivotal team leveraged Spring XD data ingestion and batch processing framework, GemFire XD & other components to solve this interesting challenge on a large 1000-node (Analytics Workbench) cluster. Using Spring XD to ingest YARN service and MapReduce application logs through a real-time data pipeline into HDFS, the team leveraged familiar SQL-based queries to analyze fine-grained cluster utilization.

The lambda architecture has been proposed as a general purpose data system that aims to solve the problem of computing arbitrary functions on an arbitrary dataset in (near) real-time. In this talk we introduce the lambda architecture and show how it can be implemented with SpringXD, GemFireXD and Hadoop (HDFS and MapReduce) as the foundation of the architecture implementation. To validate the architecture we introduce a CDR (Call Detail Record) mining application as use case of the lambda architecture. We finalise by showing a demo of the CDR (Call Detail Record) mining application.

Spring XD - A Guided Tour

Recorded at SpringOne2GX 2014.

Speakers: Patrick Peralta, David Turanski

Big Data Track

Slides: http://www.slideshare.net/SpringCentral/spring-xd-guided-tour

What happens when a Stream is deployed to a Spring XD cluster? How does Stream processing and data partitioning work? How does the cluster recover when a Spring XD container goes down? How does Spring XD create and manage application contexts? What is a Plugin? How does Spring XD support extensibility? Our experienced guides will take you on a tour of the Spring XD runtime environment, navigating Streams and observing how Modules thrive in their natural habitat. We will explore the role of ZooKeeper, Spring Integration, and Spring Boot through beautiful panoramas, code samples, and daring demonstrations.

GemFire is Pivotal's distributed In Memory Data grid. In this session we will cover simplifying configuring a GemFire grid using Spring Data GemFire, and explore how data is dynamically distributed and made highly available as the grid resources are increased or decreased to meet increased client demand. GemFire access and testing patterns using Spring will be reviewed in detail. We will walk through creating a domain object and using Spring Data GemFire Repositories to perform CRUD operations on a GemFire grid, creating a Spring MVC/Spring Boot application that uses GemFire as its persistence layer, review how Spring Boot and Spring Data GemFire can be used to help with GemFire test cases and how Spring Data GemFire can make creation and execution of GemFire functions easier. We will also explore how Spring XD can be used to load and monitor data changes in the grid. This will be a hands on, code oriented session.

The Spring Integration JavaConfig and DSL extension provides a set of convenient Builders and a fluent API to configure Spring Integration message flows from Spring @Configuration classes. The Java DSL for Spring Integration is essentially a facade for Spring Integration. The DSL provides a simple way to embed Spring Integration Message Flows into your application using the fluent Builder pattern together with existing Java and Annotation configurations from Spring Framework and Spring Integration as well. Another useful tool to simplify configuration is Java 8 Lambdas.
