timeout caused by wait for mutex

Last timeArticleWe have discussed how to design an ASP. NET web service to process persistent connection requests. Many people have asked this question. How can I hold the request and keep it open for 30 seconds? This is actually very simple. Just

Innodb is a multi-thread concurrent storage engine. internal read/write operations are implemented using multiple threads. Therefore, innodb implements a highly efficient concurrency synchronization mechanism. Innodb does not directly use the latch

April 23, 2009 In this article, we summarize five experiences based on the main features of multi-threaded programming in Linux to improve the habit of multi-threaded programming in Linux and avoid development traps. In this article, we
