Sharing practical vivo Internet technology insights and salon events, plus the latest industry news and hot conferences.
This guide walks through Pulsar's operational challenges and demonstrates how to use Ansible Playbooks—including syntax, modules, roles, variables, and task dependencies—to fully automate the deployment of Zookeeper and Pulsar clusters, dramatically reducing manual effort and configuration errors.
This article walks through a real-world slow‑SQL case, explains the inner workings of Join and Order‑by algorithms, demonstrates using EXPLAIN and optimizer_trace to trace execution, and shows how adding indexes and choosing the right join method can dramatically improve MySQL query performance.
This article analyzes the CPU spikes that occur within minutes after a Java service restart, explains how excessive Runnable threads, frequent context switches, and JIT compiler activity cause the overload, and presents step‑by‑step diagnostics and mitigation strategies such as traffic greying, cache pre‑warming, request‑parameter cleanup, and JVM warm‑up.
Vivo unveiled its BlueOS kernel, the first industry‑wide, fully Rust‑written operating system kernel open‑sourced at the 2025 Open Atom Open‑Source Ecosystem Conference, highlighting its security‑first design, lightweight footprint, cross‑architecture compatibility, and AI‑integrated features aimed at the emerging AGI era.
This article traces the century‑long journey of developer experience, beginning with Ada Lovelace’s pioneering program, through the era of wiring, punch cards, assembly, BASIC REPLs, visual editors, syntax highlighting, and modern IDEs, highlighting key milestones, code examples, and the cultural shifts that shaped today’s tooling.
This article details how the vivo Internet Big Data team systematically improved the home‑page performance of their BI data‑visualization platform by analyzing key web metrics, identifying bottlenecks, and applying time‑ and space‑focused optimizations such as HTTP/2 migration, resource preloading adjustments, code splitting, and Web Workers, resulting in a 292% overall speed increase.
During a gray‑scale upgrade, a Vivo Pulsar deployment using the KoP protocol experienced a sudden drop in partition consumption rates because the consumer group name vanished from Zookeeper nodes, prompting an in‑depth analysis of the root cause, replication steps, and three progressively refined remediation strategies.
This article systematically analyzes a Spring Boot project's 280‑second startup, identifies bottlenecks such as bean initialization and sharding data source loading, and applies listener‑based timing, bean‑post‑processor profiling, and asynchronous initialization to reduce launch time to 159 seconds, improving developer efficiency.
This article details Vivo's end‑to‑end Pulsar observability solution, covering the challenges of Prometheus‑based monitoring, the architecture of the alerting pipeline, adaptor development, metric optimizations for subscription backlog and bundle load, and fixes for kop lag reporting issues.
This article provides a comprehensive analysis of Apache Pulsar's Producer component, detailing its message-sending workflow, key design principles, configuration parameters, and practical performance tuning techniques to improve throughput, reduce latency, and lower resource consumption in large‑scale cloud‑native messaging systems.
