Enhancing MySQL: MySQL improvement project

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 mo ... Read full article.
