This Week in Spring - May 21, 2019

Engineering | Josh Long | May 21, 2019 | ...

Hi Spring fans! It's been quite a crazy week! I was in Spring I/O last week in Barcelona, Spain and there was a deluge of interesting news to come out of the show! I loved the show - a sort of mini SpringOne - and am chomping at the bit to see what comes next. I'm now beginning a small tour starting in Zurich, Switzerland; then I'm off to the paradise-like Paris, France for the epic SpringOne Tour event there, then I'm off to Minsk, Belarus; then off to Barcelona, Spain for JBCN, and then - finally - home for the middle school graduation of my kid at the end of the month. So much exciting…

Josh Long often says that “production is the best place on the Internet.” But where I used to work, developers needed to negotiate with operations, networks, and security before their code could go anywhere near this promised land.

Understandably, each of these disciplines seemed to have the same hidden agenda: change is bad. Experience had taught us that change was difficult and error-prone, so as a company we’d become risk-averse and cautious about our deployments. Releases were infrequent and large. There was plenty that could go wrong.

In spite of this, every six months or so developers would bundle up their code changes into a release, write the release notes, create a rollback plan, and wait around until midnight on a Saturday to deploy it. The deployment would be done manually, and not by developers, but by someone in operations. Developers were strictly passengers on this particular release-train (after all, we’re “the people who write all the bugs” as my friend Coté

Engineering | Josh Long | May 17, 2019 | ...

HI Spring fans! In this installment Josh Long (@starbuxman) talks to Nicolas Frankel (@nicolas_frankel) about integration testing, blogging, Kotlin, application security, living on the French/Swiss border, blogging consistently, and much more. It's an interview with one of my favorite voices in the community.

Reactive Transactions with Spring

Engineering | Mark Paluch | May 16, 2019 | ...

Back in 2016, our reactive journey started with Spring Framework 5 accompanied by a couple of reactive integrations. Throughout our journey, other projects joined the reactive movement. With R2DBC, we now also provide a reactive integration for SQL databases. With the growth of transaction-capable integrations, we constantly got asked:

Does Spring Framework support Reactive @Transaction?

At the time our journey began, we had no reactive form of transactional integrations, so this question was simple to answer: There’s no need for reactive transaction management.

Over time, MongoDB started to support multi-document transactions with MongoDB Server 4.0. R2DBC (the specification for reactive SQL database drivers) started to emerge, and we decided to pick up on R2DBC with Spring Data R2DBC. Both projects wanted to expose transactional behavior, so they eventually provided inTransaction(…)

Spring Tips: Spring Batch and Apache Kafka

Engineering | Josh Long | May 14, 2019 | ...

Hi Spring fans! Welcome to another installment of Spring Tips (@SpringTipsLive)! In this installment we look at the just-landed community contribution in Spring Batch adding support for Apache Kafka. This new support offers some tantalizing opportunities to bridge batch and streaming workloads. Stage large writes to backend warehouses with Kafka and drain the stream with Spring Batch. Load large amounts of data from existing datastores and funnel it into stream processing pipelines. And the possibilities become even more interesting when you consider Spring Integration, Spring Cloud Stream,

Hi Spring fans! Welcome to another installment of This Week in Spring! I'm in beautiful Krakow for the epic Geecon show and then I'm off to spectacular Barcelona, Spain for the Spring I/O show. I hope to see you in both locations! It's sure to be fun. Next week it's going to be even more crazy! Next week I'm off to Zurich, Switzerland for a visit with some customers, and then it's off to Paris, France for the Spring One Tour event there, and then it's off to Minsk, Belarus, for the VOXXED Days Minsk show (my first time there! I'm so excited!), and then right after that, it's off to Barcelona…

A Bootiful Podcast: Kotlin team engineer Roman Elisarov

Engineering | Josh Long | May 09, 2019 | ...

Hi Spring fans! In today's installment Josh Long (@starbuxman) sits down with Jetbrain's Roman Elizarov (@relizarov). Roman works on the Kotlin team and, among other things, focuses on asynchronous programming with things like coroutines. This interview was a very detailed dive into the opportunities for asynchronous programming for Spring developers using Kotlin, especially in light of the new coroutine support coming in Spring Framework 5.2.
