Go backend development, learning open-source project source code together, focusing on simplicity and practicality.
This article walks through building an EasyRedis service in Go, explaining Redis's lazy and timed expiration strategies, showing concrete code for on‑read expiration checks, and detailing a time‑wheel implementation that efficiently schedules key deletions.
This article walks through the third part of an eleven‑article series that implements a functional Redis‑compatible in‑memory database in Go, detailing how the PING, AUTH, SELECT, SET and GET commands are parsed, routed and executed with concrete code examples.
This article walks through implementing the Redis Serialization Protocol (RESP) in Go as part of the EasyRedis project, detailing the protocol format, parsing logic, connection handling, and a demo showing how standard redis-cli commands are encoded and processed.
This article walks through creating a lightweight Redis clone named EasyRedis in Go, covering a producer‑consumer logger, .conf file parsing with reflection, a TCP server with graceful shutdown, and demonstrates the running service via telnet, with all source code available on GitHub.
This article walks through implementing a deep‑copy function in Go with the reflect package, explaining key concepts such as reflect.ValueOf, reflect.New, pointer handling, and recursive copying, and provides a complete code example and visual diagrams.
This tutorial walks through creating a lightweight Go ORM—covering a custom logger, converting structs to table metadata, implementing basic CRUD operations, handling transactions, and adding hook callbacks—while exposing the core Session data structure and providing a GitHub reference.
This article walks through implementing EasyCache, a Go‑based in‑memory cache with sharding, lock‑free concurrency, LRU eviction, and configurable expiration, explaining the underlying data structures, goroutine cleanup logic, and key handling with concrete code examples.
This article walks through implementing three load‑balancing algorithms (random, round‑robin, weighted round‑robin) in Go, explains the weighted selection math with step‑by‑step examples, and presents two service‑liveness solutions—heartbeat via Docker/Kafka and HTTP health checks—complete with code snippets and deployment commands.
This article walks through building a simple yet enterprise‑grade key‑value storage engine in Go, covering WAL implementation, LSM‑Tree structure, SkipList‑based in‑memory storage, transaction handling for Put/Get/Delete, and the on‑disk log format, with a complete 1,000‑line codebase hosted on GitHub.
This guide walks C beginners through the TinyHttp project—providing Chinese annotations, environment setup, common pitfalls, detailed code flow, key function explanations, and step‑by‑step instructions to compile, run, and test a minimal web server.
