This article explains the concept of short‑URL redirection, its benefits, and provides a complete SpringBoot implementation—including database schema, entity, DAO, service, controller, and testing code—to convert long links into short, trackable links and handle redirects.
This article explains the motivation, architecture, resource estimation, code generation algorithms, data modeling, database partitioning, caching strategies, and implementation details for building a scalable short URL system that handles billions of links and high QPS workloads.
This article explains how to design a high‑performance short‑URL service capable of handling 1 million queries per second, covering system background, URL shortening principles, base‑62 encoding, distributed ID generation options, storage sharding, ambiguity checking with Bloom filters, multi‑level caching, and redirect handling.
This article explains how to use Sina's short URL API to convert long links into short t.cn links, detailing request formats, required parameters, example PHP code for generating and expanding URLs, and shows sample JSON and XML responses.
This article explains the value of short URLs, the HTTP redirection principle behind them, and provides detailed design and implementation strategies—including hash‑based and distributed‑ID approaches, base‑62 encoding, database storage, caching, indexing, and security measures—to build a scalable short‑link service.
This article explains the value, underlying HTTP redirect mechanism, and detailed design approaches—including hash‑based and distributed‑ID generation, base‑62 encoding, database storage, caching, indexing, sharding, and rate‑limiting—to build a scalable short‑link service.
This article explains the need for globally unique identifiers in modern applications, outlines the essential characteristics of a distributed ID generation service, examines common implementation techniques, and discusses concrete business scenarios such as order numbers, coupons, short URLs, and tracing with practical code examples.
The article explains the need for globally unique IDs in various business scenarios, outlines essential service characteristics such as uniqueness, ordering, high availability, and security, and details common technical implementations including Snowflake, Redis auto‑increment, short‑URL encoding, and custom coupon code schemes.

This article explains the benefits of short URLs, outlines their basic workflow, and details a backend design that uses an incremental issuer, base conversion, persistent storage, caching, batch ID allocation, and distributed issuers to achieve efficient, high‑concurrency short‑URL generation.
The article explains why short URLs are popular, outlines their basic workflow, and details a backend service design that uses an incremental ID generator, Redis caching, MySQL storage, batch allocation, and distributed strategies to efficiently create and manage short links.
This article explains the principles of short URL generation, compares incremental ID, hash, and random algorithms, analyzes their security and collision characteristics, and presents a complete backend design including database schema, caching strategy, sharding, and Java implementation details.
This article explains the concept of short URLs, compares three generation algorithms (auto‑increment ID, hash‑based, and random), analyzes their trade‑offs, and presents a complete backend design including database schema, caching strategy, redirection flow, and Java code examples for hash and base‑62 conversion.
This article explains the benefits of short URLs, outlines the basic workflow of generating and resolving them, and presents a complete Java implementation that uses Redis for fast storage, MySQL for persistence, and various techniques for high concurrency and distributed deployment.
Designing a short URL service involves choosing appropriate key‑value storage, simple incremental or base‑36 encoding for keys, estimating data capacity and sharding strategies, handling concurrent reads/writes with thread‑safe structures or Redis, selecting network event loops, and addressing security concerns such as abuse prevention.
