Introduction to Distributed Locking In the world of distributed systems, managing concurrent access to shared resources is a critical challenge. Imagine a scenario where multiple instances of your microservice need to access a shared database or perform some exclusive operation. This is where distributed locking comes into play, ensuring that only one process can access the resource at any given time. What is etcd? Before diving into the implementation, let’s understand what etcd is....

The Scalability Conundrum: Not Every App Needs to Be a Giant In the world of software development, scalability is often touted as the holy grail. We’re constantly reminded that our applications need to be ready to handle millions of users, scale horizontally, and perform flawlessly under any load. But what if your app doesn’t need to be the next Facebook or Netflix? What if it’s just a simple tool designed for a small, niche audience?...

When it comes to messaging systems, the choices can be as overwhelming as trying to decide which pizza topping to go for – both are crucial, and the wrong choice can lead to a culinary (or in this case, technical) disaster. In the realm of messaging, two popular contenders are Apache Pulsar and RabbitMQ. Each has its own strengths and weaknesses, and understanding these is key to making the right choice for your project....

When it comes to software development, the allure of third-party libraries is hard to resist. They promise to save time, reduce costs, and accelerate the development process. However, beneath the surface of these benefits lies a complex web of potential pitfalls that can jeopardize the integrity, security, and maintainability of your software. The Siren Song of Third-Party Libraries Third-party libraries are like the sirens of the software world, luring developers with the promise of easy solutions to complex problems....

Introduction to Distributed Locks In the world of distributed systems, managing access to shared resources is a critical challenge. Imagine a scenario where multiple servers need to update a database or modify a file simultaneously. Without proper synchronization, this can lead to race conditions, data inconsistencies, and other nightmares. This is where distributed locks come into play. Why Use Redis for Distributed Locks? Redis, with its in-memory data structure store and robust set of features, is an ideal candidate for implementing distributed locks....
