This Week in Spring - February 6th

Hi, Spring fans! Welcome to another installment of the rip-roarin’ adventure that is This Week in Spring! We’ve got a lot to look at, as usual, so let’s dive right into it!

• in last week’s installment of A Bootiful Podcast, I talked to Gunnar Morling, who created the 1BRC (1 Billion Row Challenge) that asks people to - using nothing but barebones JDK Java types - load one billion rows of weather station telemetry data. This was a race to the bottom as hundreds of entries flooded in and we eventually got implementations that loaded and analyzed and processed thirteen gigabytes of data in less than 1.5 seconds. It’s a very cool effort and Gunnar was kind enough to share some of the learnings we can take from the results
• In last week’s installment of Spring Tips, I look at the fantastic new Spring AI project.
• Baeldung have a nice blog up on custom JSON deserialization using Spring WebClient
• wanna know how Moderne, a company behind the popular OpenRewrite tool, which provides code-based recipes to refactor Java code, dogfooded OpenRewrite to upgrade their own Spring Boot codebase to Spring Boot 3.2? Look no further!
• Spring legend Craig Walls has a nice vlog on generating images with Spring AI
• Did you see this presentation I did at the AxonIQ keynote last year with Axon Framework founder Allard Buijze?
• Did you see this video I did introducing Spring Data JDBC?
• …or this one introducing DataSources?
