Introduction IntelliJ IDEA has long been considered the most intelligent Java IDE available, not because it simply provides code editing capabilities, but because it fundamentally changes how developers interact with code. Unlike traditional IDEs that focus mainly on syntax assistance, IntelliJ has always focused on understanding developer intent, which is why it remains the preferred […]
Modern applications are changing very rapidly. Traditional keyword search is no longer sufficient for many real-world use cases, including AI-Powered recommendations, semantic search, chatbots, fraud detection, and product similarity engines. These systems require the ability to understand meaning and relationships between pieces of data rather than just matching exact keywords. This is how and where
Introduction OutOfMemoryException (often seen as java.lang.OutOfMemoryError) is one of the most frustrating problems Java developers face in production. When this happens inside a Hazelcast cluster, the impact becomes even more serious nodes crash, data partitions get redistributed, performance drops, and entire applications may become unstable. Hazelcast unlike a in memory data grid, it is fast
In today’s advanced digital world, APIs are the most used modern applications, with mobile apps fetching data to large-scale enterprise systems communicating across applications using microservices. Every millisecond is counted, and network reliability plays a critical role in delivering user-friendly features. However, there are multiple factors, network communication is never perfect. Sometimes the server takes
The Spring Framework is a widely used Java framework for building enterprise applications. It brings structure, scalability, and efficiency by using Dependency Injection(DI) and Inversion of Control(IOC) to simplify component wiring and lifecycle management. Two core concepts that often used by developers are @Bean and @Components, they may look similar, but their purposes and internal
Overview In contemporary AI and ML environments, vectors are the primary way to encode and search complex, high-dimensional data such as text, images, audio, and user preferences. Starting with Hazelcast 5.4, Vector Collections let developers implement semantic search, recommendation engines, and other AI features directly inside a distributed in-memory data grid, removing the need for
Overview gRPC is a high-performance open-source remote procedure call framework, initially it was developed by Google. It is to eliminate the boilerplate code and connect with services in and across the data center. The gRPC API uses the Protocol Buffers, it uses the protec compiler to generate source code in different supported languages. gRPC services
Overview Efficient memory management is critical for any high-performing Java application, and understanding how the Java Virtual Machine (JVM) handles memory is essential for developers. The JVM manages system resources to ensure smooth operation, even as applications become more complex. This guide explores how JVM memory management works, delving into the different memory areas, garbage
Introduction In a modern application that interacts with different database and app services, handling the distributed transactions are very efficient and crucial. To manage the data consistency across the multiple resources XA transaction(eXtended Architecture) is a standard way. In this article, we will explore how to use the XA Transactions in Java using Hazelcast data
Introduction In a distributed system, maintaining data integrity and consistency is very challenging. To implement Hazelcast transaction Management, Hazelcast provides features that make it easy to manage transactions and data consistency. Hazelcast is a high-performance, in-memory data grid(IMDG) which supports distributed caching, computation, and messaging. In this article, we will explore the features of Hazelcast
