Introduction A few months back, while debugging a messy Spring Boot service at 2 a.m., I pasted a confusing error trace into a GenAI tool just to see what it would say. To my surprise, it suggested a fix that actually worked. That was the moment I realized—this technology isn’t just hype; it’s going to […]
Introduction In the competitive world of Java enterprise application development, a database connection pool is no longer a luxury; it is a requirement. While developers often focus on building complex logic and polished user interfaces, they sometimes overlook the silent workhorse of modern applications: the connection pool. HikariCP, a lighter yet more powerful JDBC pool, […]
Introduction Elasticsearch has become a go-to choice for building fast, intelligent search experiences. But what if your source of truth is a relational database like MySQL? In this blog, we’ll walk through how we migrated structured relational data into Elasticsearch using Python — with company_registry as a working example. Why Migrate from MySQL to Elasticsearch? […]
Introduction Java memory management refers to the process by which the Java Virtual Machine (JVM) allocates, organizes, and reclaims memory used by variables, methods, classes, and objects during program execution. It ensures efficient memory use by automatically managing object creation and destruction, helping developers avoid manual memory handling and common pitfalls like memory leaks. Types […]
Introduction AI tools like Cursor are powerful, but with power comes the need to be extra cautious. If you’re using Cursor in your workflow, make sure you follow these key security and best practices. A few smart checks now can save you from big headaches later. Before you import any codebase into Cursor, please take […]
Introduction Jolt is a JSON to JSON transformation library written in Java, which allows you to define or write a template that specifies a set of operations that are chained together to transform your input JSON to your desired JSON format. The idea is to transform the structure of your JSON data and not modifying […]
Imagine you’re managing a busy e-commerce website. Every time a customer places an order, it triggers several events: an email confirmation, a shipping update, a payment confirmation, and much more. From updating the inventory to sending a confirmation email and processing the payment, everything needs to happen instantly and in sync. But how do you […]
Introduction Generative AI (Gen AI) has revolutionized how machines generate text, code, images, and more by leveraging deep learning models. However, one of its key limitations is its reliance on pre-trained knowledge, which may become outdated or lack domain-specific insights. This is where Retrieval-Augmented Generation(RAG) comes into play. RAG enhances Gen AI models capabilities by […]
Imagine your coffee shop is thriving, but one location can’t keep up with the growing demand. To fix this, you open more shops across the city, easing the load. Sharding works similarly for databases. When one MongoDB server can’t handle the volume, data is distributed across multiple machines (shards), making your system more efficient. In […]
