Speaker: Monish Unni Data / Integration Track Slides: http://www.slideshare.net/SpringCentral/introducing-calltracing-tm-based-on-rabbitmq-spring-and-zipkin Do you live in a world where StackTraces aren’t quite enough? There is no easy way for you to predict how a certain set of services might be called or what their usage patterns are? Does everything work in DIT/SIT/UAT/PELT until you hit production and strange things start to happen due to distribution of services? Solution: Use RabbitMQ (AMQP protocol) and spring proxies/interceptors to enable an out-of…

I am pleased to announce that the spring-kafka (Spring for Apache Kafka) first milestone is now available (1.0.0.M1).

The existing spring-integration-kafka extension project - currently at version 1.3.0.RELEASE supports Kafka 0.8.x.x and is used in Spring XD (Kafka MessageBus) and Spring Cloud Stream (Kafka Binder).

This new project (spring-kafka) breaks out the core components into a separate project. It is based on the new 0.9.0.x pure Java Kafka clients.

spring-kafka brings the familiar Spring programming model to Apache Kafka for any Spring user, not just those using Spring Integration. An upcoming spring-integration-kafka release will be a complete rewrite, utilizing the spring-kafka…

[Update] Following our Reactor 2.5 introduction, we shifted the version to 3.0 to reflect better the major redesign effort overtaken.

A meaningful composition API

The former reactor-stream module has been merged into Reactor Core 3.0. Flux and Mono respectively representing 0..N and 0..1 sequence types now cover a solid range of operations for the following categories:

• Cold-to-Hot or Multicasting : publish, publishNext, cache, multicast...
• Aggregating/Reducing (Transforming) : buffer, reduce, scan, window, sample...
• Filtering : filter, exists, single...
• Conditioning : timeout, take, takeUntil, skip, skipUntil...
• Combining : withLatestFrom, combineLatest
• Backpressuring : onBackpressureDrop, onBackpressureLatest...

Stream Processing in the Cloud with Data Microservices Speakers: Marius Bogoevici, Pivotal

The future of scalable data processing is event-driven microservices! They provide a powerful paradigm that solves issues typically associated with distributed applications such as availability, data consistency, or communication complexity, and allows the creation of sophisticated and extensible data processing pipelines.

Building on the ease of development and deployment provided by Spring Boot and the cloud native capabilities of Spring Cloud, the Spring Cloud Stream project provides a simple and…

Speaker: Danny Hyun With the advent of Ratpack and Spring Boot, people think you need to choose between one or the other. That couldn't be further from the truth. The only place where they overlap is in serving web requests. Spring Framework is a very rich ecosystem including but not limited to DI, web mvc, data, security, etc. Ratpack focuses on rapid web app prototyping and iteration balancing low resource utilization, high performance and developer friendliness. We'll explore the ways in which Ratpack and Spring Boot work in harmony.

In this session we will discuss how Spring Integration and Spring AMQP are used as two of the underlying technologies in Spring XD.

The RabbitMQ message bus is used to dynamically create and bind queues and exchanges at runtime when modules are deployed. Items of particular interest include the provision of taps using fanout exchanges, use of the RabbitMQ REST API and spring-retry within the message bus…

The Hadoop ecosystem is getting bigger and more complex. Using multiple projects from this ecosystem, you will have to deal with the difference in philosophy and usage patterns that these project promote. The "Spring for Apache Hadoop" project uses many Spring projects like Data, Integration, Batch and Boot to resolve many of these issues. It simplifies developing for Apache Hadoop by providing a unified configuration model and…
