Full-Link Multi-Version Deployment in Testing Environments: Architecture and Practices

Vivo’s full‑link multi‑version deployment framework lets a complete microservice system be launched once while concurrently running multiple service versions in isolated baseline and on‑demand feature environments, using custom traffic‑coloring headers, tag propagation across HTTP/Dubbo/MQ, dynamic routing, and distributed tracing to reduce resource waste, accelerate hot‑fix testing, and pave the way for future data‑level isolation and production‑grade A/B experiments.

Redis Cluster Slot Migration Optimization Based on Master-Slave Replication Mechanism

Vivo’s storage team redesigned Redis cluster slot migration by disguising the target as a slave and using master‑slave replication with progressive loading, which eliminates ask‑move round trips, reduces latency spikes, consolidates topology updates, and ensures stable access and high availability during horizontal scaling.

Time Wheel Algorithm: Evolution, Implementation, and Applications

The article chronicles the time wheel algorithm from its 1997 origins, explains simple, round‑based, and hierarchical wheel designs, compares them to queue timers, details Dubbo’s HashedWheelTimer implementation, and shows how combining the wheel with a delay‑message queue can dramatically improve service scalability and efficiency.

MySQL 5.7 DDL vs GH-OST: A Comprehensive Comparison of Online Schema Change Tools

While MySQL 5.7 native DDL methods (copy, inplace rebuild, index build, metadata‑only) vary in speed, space use, lock impact, and binlog output, GH‑OST consistently offers the fastest execution, lowest lock blocking, real‑time replication, albeit at roughly double storage cost, making it ideal for risk‑averse online schema changes.

Optimizing 3D Model Loading and First‑Frame Rendering with Three.js, ZIP Packaging, and WASM Decompression

By compressing GLB files into ZIP, extending Three.js loaders to unzip via a Rust‑compiled WASM tool, encrypting small buffers, and caching morph‑target shaders while spreading mesh rendering across frames, the team shrank model size from 50 MB to 11 MB and cut first‑frame render time from 7 seconds to 0.6 seconds, reducing overall page load from 15 seconds to 5 seconds.

HBase Optimization Practice in Vivo's Unified Content Platform

Vivo's unified content platform replaced its unwieldy 60 TB MongoDB store with HBase, then upgraded the cluster, introduced table‑specific connection pools, column‑only reads, tuned compaction, and leveraged multi‑version cells, cutting response times from seconds to under ten milliseconds and dramatically lowering operational costs while boosting read/write performance.
