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

If you're missing an introduction to Reactive Streams and the basic concepts of Reactor, head out to the site's learning section and the reference guide…

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…

I am pleased to announce the release of Spring Session for Apache Geode & Pivotal GemFire (SSDG), 2.2.0.M1.

This release focuses on dependency updates to align with the rest of the Spring portfolio in their respective release lines, building on:

• Spring Framework 5.2.0.M1

• Spring Data Moore-M3

• Spring Session 2.2.0.M1

What’s Next

Some of the proposed and upcoming features in the SSDG 2.2 release line include:

• Attached Sessions (option).

• Stronger Consistency (option) using Map.replace(key, oldValue, newValue) for lightweight transactions supplanting the need for heavier, cache/local transactions.

• Improvements in PDX Serialization support.

• And much more…​

…

Hot on the heels of Spring Framework 5.2 M1 and just in time for the upcoming Spring Boot 2.2 M2 release, on behalf of the Spring Data team, I’m pleased to announce the availability of the third milestone of the Moore release train.

Notable changes amongst many others:

• Flow extensions for Kotlin coroutines in Spring Data for Apache Cassandra & MongoDB.
• MongoDB Json Schema generation from domain Types.
• Support for BINARY storage type in Spring Data JDBC.
• Alternative EntityMapper for Elasticsearch.
• Improved Geospatial query support for Neo4j.
• Smarter Redis cluster topology caching.

On behalf of the entire team I’d like to announce the availability of three service releases for Spring Data release trains: Lovelace SR6, Kay SR14, and Ingalls SR20.

The releases are recommended upgrades as they contain fixes for a CVE in Spring Data JPA.

Spring Boot 2.1.4, 2.0.9, and 1.5.20 already pull in the above Spring Data versions, including the fixes that were released last week, and are now also available for use.

Here’s the content of the releases:
