This Week in Spring - December 18th, 2018

Engineering | Josh Long | December 19, 2018 | ...

Hi Spring fans!

Welcome to another installment of This Week in Spring! I just wrapped up the last two talks or workshops I'll do this year. Yesterday we spent four hours looking at Reactive Spring and today we spent four hours looking at Spring Boot and Kotlin. I love doing these sorts of trainings because I really get to dive deep on topics with my audiences. It's, truly, one of the rare pleasures in an otherwise hectic schedule. Needless to say, I am super relaxed and happy as I write this and I hope you are too!

You realize it's already December 18th, 2018, already? Gee time flies when you're having fun! The next installment of This Week in Spring is on the 25th, which, for some in the world, is the holiday Christmas. If that includes you, then let us be the first to

Spring CredHub 2.0.0.RC1 released

Engineering | Scott Frederick | December 14, 2018 | ...

I’m pleased to announce the first release candidate of Spring CredHub 2.0.0, available now in the Spring milestone repository. A GA release of Spring CredHub 2.0.0 will be available in a few weeks.

CredHub

CredHub provides centralized credential management to the Cloud Foundry platform. CredHub implements an HTTP API to securely store, generate, retrieve, and delete credentials of various types.

Spring CredHub provides a Java binding for the CredHub API, making it easy to integrate Spring applications with CredHub.

What’s New

The 2.0.0 release includes the following enhancements:

  • Supports CredHub server versions 1.x and 2.x, and the CredHub v1 and v2 APIs

  • Provides compatibility with Spring Framework 5.1 and Spring Boot 2.1

  • Addition of a reactive interface using Reactor

How Fast is Spring?

Engineering | Dave Syer | December 12, 2018 | ...

Performance has always been one of the top priorities of the Spring Engineering team, and we are continually monitoring and responding to changes and to feedback. Some fairly intense and precise work has been done recently (in the last 2-3 years) and this article is here to help you to find the results of that work and to learn how to measure and improve performance in your own applications. The headline is that Spring Boot 2.1 and Spring 5.1 have some quite nice optimizations for startup time and heap usage. Here’s a graph made by measuring startup time for heap constrained apps:

Hi Spring fans and welcome to another installment of This Week in Spring! This week I've been in Seattle, WA and now I'm off to Toronto, Canada for the epic SpringOne Tour Toronto edition, the last SpringOne Tour for the year, too! (Can you believe we're now less than 22 days from 2019? Time sure flies when you're having fun!)

Reactive Programming and Relational Databases

Engineering | Mark Paluch | December 07, 2018 | ...

Imperative code eats threads at the pace of incoming requests while Software is eating the world. This post discusses the assumptions for reactive programming on the JVM and what this means for integrations – in particular, relational databases.

The motivation to come up with a post is the constant increase in reactive programming adoption while some major building blocks are not yet available – in particular, the question: What about relational databases?

What is Reactive Programming

There are a lot of answers about what Reactive Programming is and how this compares to Reactive Systems. I see Reactive Programming as a programming model that facilitates scalability and stability by creating event-driven non-blocking functional pipelines that react to availability and processability of resources. Deferred execution, concurrency and asynchronicity

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in Marikesh, Morocco for the epic Devoxx MA talking about all things Spring and cloud with my friends - Google's Ray Tsang and Microsoft's Bruno Borges. Then, tomorrow it's off to Bern and Zurich Switzerland [for the local JUGs there. Tonight, in about 15 minutes, I'm doing a live training on Safari - "Bootiful Kotlin," too.

As usual, we've got a ton of things to cover so let's get to it!

Hi Spring fans! How's things? I'm in Taipei, Taiwan, where I've presented at the local JUG and at the Cloud Native Forum. It's been a crazy good time on the ground eating delicious "stinky tofu" (that's its name!), trying to figure out the difference between traditional Chinese characters and so-called simplified Chinese characters used in China, and of course making tons of new friends.

In less than 24h I'll be on a plane winging my way back west where I'll join my family, and our newest addition, and our friends, and we'll celebrate the Thanksgiving holiday together. It's this time of year when I try to take stock of all the things for which I'm grateful and you know what, dear reader? Time and time again, I think of you, the community that makes Spring the best place to integrate and innovate. I am thankful for you. I'm sure I speak for the Spring team and Pivotal at large when I say, we
