Скачать или смотреть Building a Fast API with Quarkus in 7 Minutes : No talk

Quarkus is a modern framework for Java application development designed to optimize performance and efficiency in cloud and microservices applications. It adopts a "start and see" approach that enables a rapid development and deployment cycle.

What is DevService
We use the JDBC driver for PostgreSQL, but if you noticed, we never configured a local or external database. That's because Quarkus Dev Services can automatically start and manage a local PostgreSQL instance so developers can work with it without worrying about database environment setup. This accelerates development and facilitates local testing of applications.

What is Panache
Panache is an extension of Hibernate for Quarkus that simplifies Java application development with data persistence in relational databases by providing a more intuitive and concise data access layer.

Why not use the repository pattern?
In Quarkus, it's common to use the Active Record pattern, which is a software design that combines business logic and data access in a single class, making it easier to interact with the database through methods in the model class.
