Spring Boot’s auto-configuration feature is one of the most powerful aspects of the framework, enabling rapid application setup with minimal configuration by developers. Auto-configuration is accomplished by dynamically registering beans based on the presence of certain classes or properties in the application context. This process is underpinned by several design patterns, with the most prominent ones being: Conditional Configuration : Allows configuration to be selectively applied based on certain conditions. Template Method Pattern : Guides the structure of configuration while allowing flexibility in implementation. Factory Pattern : Manages bean creation and initialization. Let's explore how these patterns work together to enable Spring Boot’s auto-configuration feature and consider how different patterns might impact its behavior. 1. Conditional Configuration and the Conditional Design Pattern Spring Boot uses annotations like @ConditionalOnClass, @ConditionalOnMissingBea...

Java 23: Stream.filter Misses Performance Optimization With the release of Java 23 , developers are excited about the new features and enhancements that push the language forward. However, despite all the innovations, one key area that remains largely unchanged is the Stream.filter method in the Stream API . The filter operation is a critical tool for functional programming in Java, but it hasn’t seen the performance optimizations it desperately needs, especially when working with large datasets and parallel processing. In this blog, I will explore the existing filter implementation, why it still lags behind in performance, and what improvements could have been made in Java 23 to boost efficiency, reduce memory consumption, and scale better in modern, high-performance applications. The Current filter Implementation in Java 23 Java’s Stream API offers a declarative way to process collections, and the filter method plays a pivotal r...
