Go backend development, learning open-source project source code together, focusing on simplicity and practicality.
The article walks through Go’s context package, explaining how Context objects enable cancellation and timeout control in concurrent workflows, detailing the implementations of emptyCtx, cancelCtx, timerCtx, and valueCtx, and providing concrete code examples and internal mechanics.
This article explains how Go's singleflight utility uses a lock and map to deduplicate concurrent calls, walks through its core structs and the Do method implementation, and shows how it improves system availability during traffic spikes.
The article explains why parallel RPC calls are needed for assembling complex objects, introduces a Go‑based MapReduce framework, walks through concrete code examples for product detail retrieval and UID cleaning, and details the internal architecture—including generate, mapper, reducer, and cancellation mechanisms—while providing full source snippets and execution flow.
This article presents a concise 70‑line Go implementation of a coroutine pool, explaining its design, how it manages task queues and worker goroutines, handles timeouts, and provides the full source code for easy integration.
This article explains how to build a TCC‑style distributed transaction layer for Redis using Go, detailing the two‑phase commit workflow, handling of prepare, commit, and rollback phases, the associated consistency challenges, and providing full code examples.
This article walks through creating a functional Redis service called EasyRedis, focusing on implementing a distributed cluster with a consistent‑hash algorithm in Go, including detailed code examples, node mapping, command routing, and relay mechanisms.
This article walks through the design and Go implementation of a reusable Redis connection pool, covering the pool data structure, object acquisition and release logic, handling of active limits and waiting queues, and an extended per‑IP socket pool for distributed Redis clusters.
This article walks through building a functional Redis server in Go, focusing on transaction support (MULTI, EXEC, WATCH, UNWATCH, DISCARD), using locks for atomicity, version tracking for watch, and an undo‑log mechanism for rollback, with code examples and demo screenshots.
This article walks through implementing a Redis pipeline client in Go, explaining how to reuse a single TCP socket for multiple requests, preserve send‑receive order, and handle sending, receiving, heartbeats, and reconnection with a concise 200‑line codebase.
This article walks through implementing a Redis‑compatible sorted‑set in Go, covering requirement analysis, data‑structure design with a map and skiplist, detailed insertion and search algorithms, complete code examples, and edge‑case handling, all illustrated with diagrams and sample output.
