Top Architect focuses on sharing practical architecture knowledge, covering enterprise, system, website, large‑scale distributed, and high‑availability architectures, plus architecture adjustments using internet technologies. We welcome idea‑driven, sharing‑oriented architects to exchange and learn together.
This guide explains what a Raspberry Pi Zero W is, lists its hardware specs, walks through downloading and flashing Raspbian Lite, enabling head‑less SSH and Wi‑Fi, configuring apt sources, installing and testing nginx, and exposing the server to the internet via an ngrok tunnel.
This guide shows how to set up MySQL InnoDB ReplicaSet, start MySQL Router 8.2, configure read/write split routing, and verify that reads are directed to replicas while writes go to the primary instance, all without modifying application code.
This guide walks through the SQL query processing workflow, explains how parsing, optimization, and execution plans affect performance, and provides concrete techniques—such as selecting specific columns, avoiding DISTINCT, using proper indexes, preferring EXISTS over COUNT, limiting result sets, and replacing HAVING with WHERE—to dramatically speed up queries while keeping statements concise.
Cloudflare abandoned Nginx for its home‑grown Rust‑based proxy Pingora, detailing the architectural limits of Nginx, the design choices behind Pingora, and the measurable performance, efficiency, and safety gains achieved in production across billions of requests.
Faced with limitations of existing tools like Quartz, XXL-Job, and PowerJob, the author explains the motivation for creating a custom scheduling framework, describes its architecture—including gRPC communication, protobuf serialization, a self-implemented name server for load balancing, a simple message queue, and time-wheel scheduling—provides code examples, and shares diagrams of discovery and dispatch processes.
This article shows how to eliminate most try‑catch blocks in Java Spring applications by using @ControllerAdvice, custom assertion utilities, and enum‑driven error codes, providing a clean, internationalized error‑response format and even turning 404s into catchable exceptions.
This article presents a step‑by‑step experiment that uses JMeter to generate 20,000 HTTP calls against a SpringBoot 2.5.4 service, captures detailed GC logs, calculates the heap memory allocated per request, analyses the impact of request payload and logging, and offers practical tuning recommendations.
A severe production incident caused duplicate order IDs due to a flawed custom Snowflake implementation, prompting a detailed review of the standard algorithm, identification of critical design mistakes, and a set of practical recommendations for safe, scalable ID generation in distributed back‑end systems.
This article introduces a ServiceManager component that uses Lambda expressions to automatically inject services, handle logging, cache service metadata, and manage exceptions, allowing Spring Boot controllers to call service methods with a single line of code.
This article explains the design and implementation of a generic asynchronous processing SDK for Java, covering its purpose, advantages, core principles, component choices, design patterns, configuration via Apollo, usage steps, safety considerations, and provides complete SQL and Spring configuration examples along with a GitHub repository link.
