Advanced Troubleshooting of MySQL Query Latency and Index Usage with eBPF: Scripts and Methodologies

Using eBPF (extended Berkeley Packet Filter) for troubleshooting MySQL query latency and index usage is a sophisticated technique that leverages Linux's advanced tracing capabilities. eBPF allows you to trace system and application-level metrics without significant performance overhead [...]

Optimizing Complex SQL Joins in MySQL: The Impact of Multicolumn Indexes on Execution Plans

Multicolumn indexes, also known as composite indexes in MySQL, can significantly impact the execution plans of complex SQL JOIN operations. These indexes are defined on two or more columns of a table and can be highly effective in optimizing queries that involve conditions on those columns. […]

Troubleshooting MySQL Query Performance with Strace: A Practical Guide

After following the steps outlined in this guide, you should be able to diagnose and optimize the performance of a specific MySQL query using strace. By tracing the MySQL thread and analyzing the system calls captured in the mysql_strace.log file, you can identify potential bottlenecks and take appropriate optimization steps. […]

Unlocking MySQL’s Performance Potential: Navigating the Impact of Queue Waits and Optimizing for Peak Efficiency

Queue waits in MySQL occur when processes or threads wait in a queue before execution. This typically happens when system resources are overutilized, and the server cannot immediately process incoming requests. Queue waits can significantly impact MySQL performance, especially in high-concurrency environments. […]
