Consistent hashing is a technique used in distributed systems to evenly distribute data across a cluster of nodes, minimising the amount of data that needs to be relocated when nodes are added or removed. This method ensures that the system remains scalable, fault-tolerant, and efficient. Introduction In a large-scale distributed system, data does not fit … Read full article: Consistent Hashing: An In-Depth Guide
Back of the envelope calculations are invaluable in the early stages of system design. These rough, rapid estimates provide ballpark figures that help engineers and architects quickly assess feasibility and compare multiple approaches, guiding more detailed analysis and design. What Are Back of the Envelope Calculations? Back of the envelope calculations are quick, simplified estimates … Read full article: Back of the Envelope Calculations for System Design: A Practical Guide

Dependency Inversion Principle (DIP), Dependency Injection (DI), and Inversion of Control (IoC) are pivotal concepts in software development, shaping the architecture and flexibility of modern applications. What is a dependency? A state where one class depends on another is called dependency or coupling. Example Class A is dependent on Class B, i.e. Class A has to create … Read full article: Dependency Dynamics: Unveiling DIP, DI, and IoC
Design patterns are crucial in enhancing code quality, maintainability, and scalability. One of the most influential collections of design patterns is the Gang of Four (GoF) patterns, encapsulated in the seminal book “Design Patterns: Elements of Reusable Object-Oriented Software.” What are Design Patterns? Design patterns are proven solutions to common problems encountered in software design. … Read full article: Understanding the Gang of Four (GoF) Design Patterns
A bloom filter is a probabilistic data structure that is based on hashing. It is extremely space efficient and is typically used to add elements to a set and test if an element is in a set. However, the elements themselves are not added to a set. Instead, a hash of the elements is added … Read full article: Bloom Filters: A Comprehensive Guide
