Understanding JPA and Other Query Construction Frameworks

Posted: 15 Jun 2021 09:18 AM PDT

JPA is the standard that guides the developer towards an object conceptualization of his application and provides him with an abstraction of the relational model. However, once the model is in place, several frameworks are available to generate the request or the command. Which choices are the most relevant? Let's explore.

Criteria JPA2

Once your dependencies are added, the Criteria API is immediately available. It is the most basic and requires knowing the API and its subtleties to produce requests. The use of these objects obliges to pass directly in character string the name of the attributes in order to impose restrictions. Errors are therefore quite frequent during development and during refactoring operations. Plus, because these errors happen at run time, they are often caught too late.

Making portable functions across serverless platforms

Posted: 15 Jun 2021 07:04 AM PDT

The rising popularity of serverless development alongside the increased adoption of multi- and hybrid-cloud architectures has created a lot of competition among platforms. This gives developers many choices about where they can run functions on serverless platforms—from public managed services to on-premises Kubernetes.

If you've read my previous articles about Java serverless, you learned how to get started developing Java serverless functions with Quarkus and how those serverless functions can be optimized to run on Kubernetes. So what should you do next to make your serverless functions fit better with the many choices available to you?
