Hi, Spring fans! Welcome to another installment of This Week in Spring! This week, I just returned from Western Europe for Devoxx FR (Paris) and Kotlin Conf (Amsterdam). I went home, saw my family, did some laundry, and then turned right back around to head to Chicago, Illinois, for a special joint session of the Chicago Kotlin and Java Users Group tonight where I'll be copresenting with my pal, field CTO Justin Reock. It's going to be a ton of fun! Don't miss out!

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.

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…

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 …
