If you ask an engineer how to solve your performance issue, the answer will depend on the engineer specialization. The range of available tools and technologies is quite big, today I’ll tell you about our experience of applying huge pages u…
In our previous blog post we discussed the purpose of a thread pool, various approaches to implementing a thread pool, along with a simulation model describing thread pool implementations in MariaDB and Percona Server. In this post we will
If you are running MySQL as a Kubernetes pod or a Docker container, there is a chance you are using CPU quota to limit its resource usage. Which is also typical for cloud environments. But do you know what kind of issues you may see when ru…
This is a blog post version of our paper “Simulation of thread pool for database server” that will be published in CEUR Workshop Proceedings. In the article, we consider an object-oriented simulation model for thread pool. The implementatio…
