JPA 2.1 Entity Graphs
Spring Data JPA makes querying easy, but the typical use case is to use lazy loading on child records, which can result in performance issues, such as the dreaded "N+1 selects" problem. JPA 2.1 introduced Entity Graphs, allowing you to explicilty state which entities get loaded at runtime, resulting in highly performant query joins. We’ll take a look at how to implement Entity Graphs in the context of a Spring Boot application.
Let me know if you’ll help out by sponsoring pizza. Thanks, Mike Levin

Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.

Aaron Erickson at QCon AI NYC 2025 emphasized treating agentic AI as an engineering challenge, focusing on reliability through the blend of probabilistic and deterministic systems. He argued for clear operational structures to minimize risks and optimize performance, highlighting the importance of specialized agents and deterministic paths to enhance accuracy and control in AI workflows.

AWS has recently introduced regional availability for the managed NAT Gateway service. The new capability allows developers to create a single NAT Gateway that automatically spans multiple availability zones (AZs) in a VPC, providing high availability, eliminating the need to define separate gateways and public subnets in each zone.
