Enhancing MySQL: MySQL improvement project

Summary

Enhancing MySQL: Performance, Stability, and High Availability To better serve MySQL users, we have optimized MySQL 8.0 comprehensively. The specific optimizations include improvements to InnoDB storage engine scalability, redo log optimization, resolution of the join performance degradation issue since version 8.0.28, optimized hash join cost model (MySQL 8.0.42+) for better execution plans, mitigation of bulk insert performance issues, resolution of performance degradation issues in certain scenarios related to query execution plans, binlog group commit optimization, memory usage optimization, high availability enhancements, and secondary replay architecture optimization. These improvements are based on data structures, algorithms, and logical reasoning, aiming for simplicity and efficiency while streamlining the MySQL optimization process. Extensive testing has shown that these optimizations are especially effective on high-performance hardware. The optimized MySQL 8.0 delivers more stable and efficient service to users. Why choose our open-source products? While enjoying the latest official features, our version offers superior performance, stability, and high availability compared to the official release. After the official release of MySQL 8.0, we can launch a high-performance integrated version within one week. We provide two-dimensional version maintenance. Each release fixes critical bugs and continuously enhances performance, ensuring users don't need to upgrade across major versions to solve issues. We continuously track and fix key performance issues, delivering high-quality service. While ensuring high availability, we provide practical strong consistency reads, with the additional latency typically only in the millisecond range. Available Download Versions In addition to the main project's patch, we also offer source code downloads and runnable versions for the subordinate releases.
