The modular monolith architecture represents a strategic middle ground between traditional monoliths and microservices, organizing Java applications into well-defined, independent modules within a single deployable unit while maintaining clear boundaries and reducing operational complexity. Modular monolith with Java has emerged as a pragmatic architectural approach for development teams seeking to escape the limitations of traditional […]

Global error handling and RFC 7807 (Problem Details) provide a standardized approach for APIs to communicate errors consistently, enabling clients to understand and process failures predictably across different services and platforms. Global error handling and RFC 7807 (Problem Details) represent a fundamental shift in how modern APIs communicate failures to their consumers. Instead of relying […]

Modern design patterns like Strategy and Factory combined with dependency injection create flexible, testable, and maintainable code architectures that adapt seamlessly to changing business requirements without breaking existing implementations. Modern design patterns like Strategy and Factory with dependency injection represent a powerful combination that transforms how developers build scalable applications. These patterns solve common software […]

Java Records are a special class type introduced in Java 14 that automatically generates immutable data carriers with built-in methods, reducing boilerplate code while enforcing best practices for data integrity and thread safety. Java Records represent one of the most significant improvements in modern Java development, transforming how developers handle data objects. Instead of writing […]

OpenTelemetry provides a standardized framework for collecting traces, metrics, and logs from Java applications, enabling comprehensive monitoring and troubleshooting across distributed systems through vendor-neutral instrumentation. Observability in Java with OpenTelemetry has become essential for modern application development, especially in microservices architectures. As systems grow more complex, understanding what happens inside your applications becomes critical for […]

Observabilidade em Java com OpenTelemetry é uma abordagem que permite coletar métricas, traces e logs de aplicações Java de forma padronizada, facilitando o monitoramento e diagnóstico de problemas em sistemas distribuídos. Observabilidade em Java com OpenTelemetry transformou a maneira como desenvolvedores monitoram aplicações modernas. Você já se perguntou como grandes empresas conseguem identificar problemas em […]

Testcontainers revolutionizes integration testing by replacing fragile database mocks with real, lightweight containerized instances that run during test execution, ensuring accuracy and reliability. Testcontainers has emerged as a game-changer for developers tired of maintaining brittle database mocks that break with every schema change. This testing library allows teams to spin up real database instances inside […]

The N+1 query problem occurs when JPA/Hibernate executes one query to fetch parent entities and then N additional queries to load their associated collections, drastically impacting application performance and database load. Solving the N+1 query problem in JPA/Hibernate represents one of the most critical performance optimizations developers face when building data-intensive applications. This common pitfall […]
