Factory pattern, first introduced by GOF in there timeless classic GOF book as creational pattern offers lot of advantage over public constructor for creating objects. It not only encapsulate logic of object instantiation, but also enforce use of tried and tested design principles like programming for interface than implementation by returning super type of objects.

Database Per Microservice Pattern in Java - Example Tutorial

Hello guys, in the last article, I share with your 10 essential Microservice design patterns and principles and best Microservices courses for Java developers which many of you appreciated. At the same time, a lot of you asked me to go deep down into each of those patterns and explain them with examples. So I decided to create this new series of Microservice Pattern tutorials where I will explain each of those essential Microservice pattern with example every week. In this article, let's have a look at what is database per microservice. Microservice architecture is a combination of a set of loosely coupled microservices and each service can be developed independently in an agile manner. We can use this pattern and practices when designing microservices. So let's go deep into what is database per microservice is and why we use it in our programming. 

What is API Gateway Design Pattern in Microservices? With Examples

Hello guys, if you are creating Microservices then you may know that API Gateway Design Pattern is a pattern that has emerged as a popular solution for managing APIs in a microservices architecture.

To address this challenge, API Gateway Design Pattern provides a single entry point for all the APIs in a microservices architecture. In the past, we have learned about Database Per Microservices, SAGA, CQRS, Event Sourcing, and Circuit-breaker pattern and in this article, we'll discuss the API Gateway Design Pattern in microservices and provide examples of how to implement it.

What is Event Sourcing Design Pattern in Microservices? Event Sourcing and CQRS Architecture

Hello guys, In the world of microservices architecture, Event Sourcing Design Pattern is gaining increasing popularity as a way to manage data and processes across multiple services. This pattern, which is based on the idea of storing events rather than just the current state of an object, allows developers to build scalable, fault-tolerant, and event-driven systems. In the past, we have learned about Database Per Microservices, SAGA, CQRS, API Gateway, and Circuit-breaker pattern and in this article we will learn about the Event Sourcing Design Pattern in Microservices Architecture. Event Sourcing is a design pattern that is commonly used in microservice architectures to manage and store changes in the state of a system. As I said, It is based on the concept of capturing and storing all changes (events) made to the system as a sequence of events, rather than just the current state of the system.

Why I Let CodeRabbit Be My First Line of Code Review (And You Should Too)

Hello guys, in software engineering, code review is both sacred and tedious. We all know it’s one of the most effective quality gates: bugs are caught early, knowledge is shared, and code consistency is enforced. But the reality is many reviews get bogged down in nitpicks, inconsistent feedback, or review fatigue. Reviewers get overwhelmed. Authors get frustrated. The process slows down. That’s why I recently added CodeRabbit to my workflow — and over months of using it, it's become my first line of defense in every pull request. It doesn’t replace human judgment, but it elevates the starting point of review. 

How I Use CodeRabbit to Level Up My Team’s Code Reviews (and How You Can Too)

Hello guys, while a lot of people are saying AI is making coding easy and there is a lot of productivy gain can be achieved by using AI for coding, I am putting my money on AI driven code review because of what I have seen. While AI can write 1000 line of code in 1 minutes but how many bugs are in their is not easy to figure out, unless you have great code reviewers and code review process but that has its own challenges. Code reviews are supposed to make code better. In reality they’re often slow, inconsistent, and noisy — especially as teams grow. To solve that problem, I started using an AI assistant, CodeRabbit, to handle the repetitive parts of reviews so humans could focus on design, correctness, and trade-offs.
