Background

When using a microservices architecture to build our applications, it is very common to end up with a pretty complex dependency tree amongst services. If the service down the dependency tree encounters an issue that causes it to start to respond slowly, it ends up causing a set of issues that cascade up the dependency tree. As more and more requests come in to the application, more and more resources may be consumed by waiting for the slow service to respond. Even worse, the additional load being put on the slow service may exacerbate the problem. To help alleviate the effect of…

We've got a ton to get to this week, as usual, so let's get to it.

This blog post is the second in a series of posts that aim at providing a deeper look into Reactor's more advanced concepts and inner workings.

It is derived from my Flight of the Flux talk, which content I found to be more adapted to a blog post format.

I'll update the table below with links when the other posts are published, but here is the planned content:

1. Assembly vs Subscription
2. Debugging caveats (this post)
3. Hopping Threads and Schedulers
4. Inner workings: work stealing
5. Inner workings: operator fusion

Here's the first Spring Tips installment introducing the "raw" RSocket protocol and Java client library

Since we announced Spring Framework official support for Kotlin in January 2017, a lot of things happened. Kotlin was announced as an official Android development language at Google I/O 2017, we continued to improve the Kotlin support across Spring portfolio and Kotlin itself has continued to evolve with key new features like coroutines.

I would like to take the opportunity of the first milestone of Spring Framework 5.2 to give a status overview of where we are when it comes to Spring and Kotlin. And I will make my best to focus on concrete improvements since I believe Spring and Kotlin share…
