This Week in Spring - April 11th, 2023

Engineering | Josh Long | April 11, 2023 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring! As I write this I am in Amsterdam, Netherlands, preparing to speak at the Utrecht JUG tonight along with fellow Java Champion Trisha Gee. We're not speaking together, but instead it's a double header: she'll speak first, then I after. I am super excited to learn from her! Then, I join James Ward and we'll speak at Kotlin Conf. Then, I take a quick train to Paris to speak at Devoxx Fr. I hope if you're about you'll join me at any of these talks.

Context Propagation with Project Reactor 3 - Unified Bridging between Reactive and Imperative

Engineering | Dariusz Jędrzejczyk | March 29, 2023 | ...

This post is a part of a series:

  1. The Basics
  2. The bumpy road of Spring Cloud Sleuth
  3. Unified Bridging between Reactive and Imperative

We concluded the last article with the thought that Spring Cloud Sleuth’s MANUAL context propagation strategy is both performant and provides correct semantics. Out of many experiences, the Spring, Micrometer, and Reactor teams created a new context-propagation library. Its goal is to encapsulate the concern of transporting contextual data between ThreadLocal values and Map-like structures. Both Micrometer 1.10 and Reactor 3.5 build on top of it to provide a first-class experience between Reactor and imperative code. By using Reactor Context, we implicitly expose ThreadLocal

Context Propagation with Project Reactor 2 - The bumpy road of Spring Cloud Sleuth

Engineering | Dariusz Jędrzejczyk | March 28, 2023 | ...

This post is a part of a series:

  1. The Basics
  2. The bumpy road of Spring Cloud Sleuth
  3. Unified Bridging between Reactive and Imperative

Spring Cloud Sleuth recently became Micrometer Tracing, part of the Micrometer project. Most of the tracing instrumentation is centered within Micrometer under the new Observability API. The goal of these projects is to enable observability of any application – in the form of metrics, tracing, and logs that contain correlation identifiers. To achieve this goal, libraries require a way to transport contextual information. When applications deal with asynchrony in any form, that task becomes quite a challenge. In the previous article, we went through the basics of context propagation with

This Week in Spring - March 28th, 202

Engineering | Josh Long | March 28, 2023 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring! I'm reporting to you from Los Angeles, where my family and I have gone for my daughter's spring break. We're going to survey some prospective colleges and we're going to Disneyland. Needless to say, I'm doubly glad to have all this cool stuff to read this week; I can really savor each article! Let's dive in!

Context Propagation with Project Reactor 1 - The Basics

Engineering | Dariusz Jędrzejczyk | March 27, 2023 | ...

This post is a part of a series:

  1. The Basics
  2. The bumpy road of Spring Cloud Sleuth
  3. Unified Bridging between Reactive and Imperative

Spring Boot 3 and Spring Framework 6 brought us a unified and consistent way to enable Observability in applications that use Micrometer. The evolution from Spring Cloud Sleuth to Micrometer, along with the Observation API and Micrometer Tracing, made us consolidate various approaches to context propagation. In this blog post series, we aim to explain how we came to support context propagation in Project Reactor to meet the needs of imperative libraries. By…

Start from zero and scale to zero – Azure Spring Apps consumption plan

Engineering | Josh Long | March 22, 2023 | ...

We are launching a new way to pay for Azure Spring Apps -- the consumption pricing plan. This plan is now in public preview so you can start creating and deploying apps today. This new plan is super-efficient because you can start from zero and scale to zero vCPU. You get more straightforward pricing across your containerized applications since it costs the same as Azure Container Apps, but with added value for Spring apps.

How does this work? With the new plan, you can deploy apps that don’t need to run all the time or apps that have bursts of traffic and only pay for the resources used…
