On the heels of the recently announced Spring Cloud Stream Elmhurst.RELEASE, we are pleased to present another blog installment dedicated to Spring Cloud Stream’s native integration with the Apache Kafka Streams library. Let’s review the new improvements.

MessageChannel Binders

Spring Cloud Stream framework enables application developers to write event-driven applications that use the strong foundations of Spring Boot and Spring Integration. The underpinning of all these is the binder implementation, which is responsible for communication between the application and the message broker. These binders are MessageChannel…

With the latest Spring Data Lovelace Milestone 2 release, the MongoDB module is stacking up new features that are coming your way in the near future. As you might have followed in the news, MongoDB 4 is going to bring ACID transactions to the Document store. The latest MongoDB 3.6 server release already ships with the main building block for those, client sessions.

You can read all about isolation levels and causal consistency in the MongoDB reference. In short, sessions let you execute operations in an order that respects their causal relationships.

With Spring Data MongoDB, ClientSession is right at your fingertips for both the imperative and the reactive world, as we have incorporated those into the already existing MongoOperations and ReactiveMongoOperations. To provide you with the utmost control and still enough convenience, managing the ClientSession lifecycle is up you, while the template takes care of passing the session on to the driver correctly. The following example shows how to create a ClientSession…

Hi Spring fans! In this installment we look at the many facets of Redis, the distributed data structure server. Spring supports Redis through the Spring Cache abstraction, Spring Session, the Spring message-listener container abstraction, and through the Spring Data Redis module.

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in Paris, France and I'll be in Mainz, Germany, next week for JAX and Linz, Austria for the DevOne event. If you're in any of these places then don't hesitate to reach out!

We've got so much to cover so let's get to it!

• Spring Cloud Task and Spring Batch lead Michael Minella just announced Spring Cloud Task 2.0.0.RC1
• Artem Bilan looks at what's new in the Spring Cloud GCP 1.0.0.M3 release.
• Spring Tool Suite lead Martin Lippert just announced Spring Tool Suite 3.9.4
• Spring Boot lead Phil Webb is cooking up a very interesting project to ensure code-formatting consistency for all Spring Boot projects. Interesting! (and still super early days yet..) Think of this as the Java and Spring Boot equivalent of gofmt.
• Spring Data ninja Mark Paluch just announced Spring Data Lovelace M2. This release ships with updates for all store modules that contain new features, improvements, and bug fixes. Notable changes include: MongoDB 3.6 support for Change Streams, $jsonSchema, and Client Sessions (in preparation for MongoDB Transactions); Apache Cassandra mapping improvements for Map and Tuple Types, along with newly introduced Lifecycle Callbacks; Upgrade to Apache Solr 7; Improved Connection Handling…

Dear Spring Community!

It’s my pleasure to announce Milestone releases for Spring projects supporting Amazon Web Services: Spring Integration for AWS 2.0.0.M2 and Spring Cloud Stream Binder for AWS Kinesis 1.0.0.M2.

Both milestones are available in the Spring Milestone repository and they can be consumed as maven dependencies:

<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-aws</artifactId>
    <version>2.0.0.M2</version>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-stream-binder…

We are pleased to announce that Spring Cloud Task 2.0.0.RC1 is now available on Github and the Pivotal download repository. Many thanks to all of those who contributed to this release.

What's New?

This release includes upgrades to existing dependencies as well as some nice new features. Let's take a look at what's new in this release.

Compatibility with Spring Cloud Stream 2.0

Spring Cloud Stream 2.0 was released a few days ago and provides a collection of impressive enhancements. Spring Cloud Task is updated and supports Spring Cloud Stream 2.0

Multiple DataSource Sample

A common point of confusion for Spring Cloud Task is how to configure a task application when using multiple DataSource beans. In this release, we provided a sample that demonstrates how that should work. You can find that sample here…

Dear Spring Community!

The Spring Cloud GCP is a set of Spring Boot starters that is designed to help you leverage Google Cloud Platform managed services directly from Spring Boot, allowing you to use Spring Messaging for Cloud Pub/Sub, Spring Resource for Cloud Storage, Spring Cloud Sleuth for Stackdriver Trace, Spring Data with Cloud SQL, and more.

We’ve just released Spring Cloud GCP 1.0.0.M3. Check out what’s new since the previous Milestone 2!

Spring Boot 2.0 GA Support

Spring Cloud GCP 1.0.0.M3 is now up to date to work with Spring Boot 2.0.1.RELEASE and Spring Cloud Finchley.M9.

To use Spring Cloud GCP 1.0.0.M3, simply import the BOM in your Spring Boot 2.0…
