What Grabbed My Attention — December 9, 2023

Here are a few (random) items that grabbed my intention this week, 3 Dec.— 9 Dec., 2023. These are headlines, articles, blog posts, news and anything that interested me this week. Enjoy.

DALL·E

Java / Spring / JVM

• Must Know Features in Java 21 — covered often elsewhere, but this one does a good job summing the Java 21 changes.
• Loading Initial Data with Spring — very useful article, also for initializing data for tests.
• SpringBoot with ElasticSearch — throws in Kibana, using ES as a backend.
• Jackson Object Mapper — introductory tutorial, always great to read through even if you know most of it.
• Spring Cloud Azure — starting some work with Azure so this was super interesting for me.

Cloud / K8 / Containers / Platform / Serverless

Database / Integration / Messaging / API / Search

• Data Engineering Design Patterns — an online book, in progress, covering data engineering.
