DESCRIPTION This book is a complete guide to designing and implementing scalable, secure, and modern APIs in a microservices architecture. Covering both synchronous communication via REST, GraphQL, and gRPC, as well as asynchronous communication with Kafka, it equips you with the tools to build efficient, reliable, and observable APIs. Learn best practices for designing REST APIs, including HTTP verb usage and the API-first approach. Explore Spring Boot technologies like WebFlux and virtual threads to build scalable REST APIs. The book also demonstrates how to use Spring Cloud Stream for broker-agnostic asynchronous communication to build robust event-driven architectures. To ensure observability, you will implement logging, monitoring, and tracing with Grafana, Prometheus, and Tempo. Security is key, and the book covers OAuth2 and OpenID Connect using Spring Security and Keycloak for centralized authentication. Finally, discover how to deploy microservices with Docker and Kubernetes, mastering containerization and orchestration.

This book is a collection of developer code recipes and best practices for persisting data using Spring, particularly Spring Boot. The book is structured around practical recipes, where each recipe discusses a performance case or performance-related case, and almost every recipe has one or more applications. Mainly, when we try to accomplish something (e.g., read some data from the database), there are several approaches to do it, and, in order to choose the best way, you have to know the implied trades-off from a performance perspective. You’ll see that in the end, all these penalties slow down the application. Besides presenting the arguments that favor a certain choice, the application is written in Spring Boot style which is quite different than plain Hibernate. Persistence is an important set of techniques and technologies for accessing and using data, and this book demonstrates that data is mobile regardless of specific applications and contexts. In Java development, persistence is a key factor in enterprise, ecommerce, cloud and other transaction-oriented applications. After reading and using this book, you'll have the fundamentals to apply these persistence solutions into your own mission-critical enterprise Java applications that you build using Spring. What You Will Learn Shape *-to-many associations for best performances Effectively exploit Spring Projections (DTO) Learn best practices for batching inserts, updates and deletes Effectively fetch parent and association in a single SELECT Learn how to inspect Persistent Context content Dissect pagination techniques (offset and keyset) Handle queries, locking, schemas, Hibernate types, and more Who This Book Is For Any Spring and Spring Boot developer that wants to squeeze the persistencelayer performances.
