What is gRPC? Imagine you’re at a high-speed racing track, and instead of driving a vintage car, you’re behind the wheel of a sleek, modern sports car. That’s what gRPC feels like compared to traditional REST APIs. Introduced by Google in 2015, gRPC is a modern, high-performance RPC (Remote Procedure Call) framework designed to facilitate communication between client and server using Protocol Buffers and HTTP/2. Protocol Buffers: The Secret Sauce Protocol Buffers, or protobufs, are the data exchange format that makes gRPC so efficient. Unlike JSON, which is text-based and flexible but slower, protobufs are a strongly typed binary data interchange format. This means you define the data contract between multiple systems and compile it to a target programming language, ensuring consistency and speed. ...

Что такое gRPC? Представьте, что вы на трассе для высокоскоростных гонок, и вместо старого автомобиля вы управляете современным спортивным автомобилем. Вот как feels gRPC по сравнению с традиционными REST API. Представленный Google в 2015 году, gRPC - это современный, высокопроизводительный RPC (Remote Procedure Call) фреймворк, предназначенный для облегчения связи между клиентом и сервером с помощью Protocol Buffers и HTTP/2. Protocol Buffers: Секретный Ингредиент Protocol Buffers, или protobufs, - это формат обмена данными, который делает gRPC так эффективным. В отличие от JSON, который является текстовым и гибким, но медленным, protobufs - это сильно типизированный бинарный формат обмена данными. Это означает, что вы определяете контракт данных между несколькими системами и компилируете его в целевой язык программирования, обеспечивая согласованность и скорость. ...

Introduction to Go and Online Interviews In the era of remote work, conducting online interviews has become the norm. If you’re looking to build a platform for this purpose, you might want to consider using Go (also known as Golang) due to its simplicity, efficiency, and robustness. Go, developed by Google, is particularly well-suited for networked and server-side applications, making it an ideal choice for creating a scalable online interview platform. ...

Introduction to Event Sourcing Event Sourcing is a design pattern that captures the history of an application’s state as a sequence of events. Instead of storing just the current state, you store every state change as an immutable event. This approach provides a robust mechanism for auditing, debugging, and even recovering from errors. In this article, we’ll dive into implementing Event Sourcing in Go, with practical examples and step-by-step instructions. ...

Introduction to the Outbox Pattern In the world of microservices, ensuring reliable message delivery is akin to navigating a minefield blindfolded. You never know when a message might get lost in the void, leaving your system in an inconsistent state. This is where the Outbox pattern comes to the rescue, providing a robust solution to guarantee that your messages are delivered, no matter what. The Problem Imagine you’re in a happy path scenario where everything works smoothly: your service performs a database transaction and then sends a message to another service or a message broker. However, things can quickly go awry. If the transaction succeeds but the message fails to reach its destination, you’re left with an inconsistent system. Conversely, if the transaction fails after the message has been sent, you might end up with duplicate messages or lost data. ...
