MySQL Transaction Reporting In chapter 8 of my forthcoming book (more on this later), I discuss reporting MySQL transactions (among many other related topics). In the book, I note that the state of the art is practically nonexistent: transactions are important, but we just don’t monitor or report them in the world of MySQL. Historically (in older versions of MySQL), there was basically no way to do this because neither the general log nor the slow log printed transaction IDs…. Read more

Recently a Customer Asked “Are there any issues with running a specific node with parallel apply enabled, and the rest of the nodes using a single stream (parallel disabled)? Just curious because that would be easiest for A/B testing of the replication effects.” In this blog post we explore the implications and best practices for using Parallel Apply on a single node in the cluster. Firstly, the answer is yes, you may certainly enable Parallel Apply on a single node within a Tungsten Cluster. The caveat is that a node with Parallel Apply enabled cannot be a provisioning source for… Read more

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 implementation of thread pool in MariaDB and Percona Server was taken as a basis. Model’s input flow and their distributions are described. Model’s output results are consistent with known “concurrency level – throughput” dependency patterns for IO- and CPU-bound workloads. The model is written in C++ and its software architecture is also considered, including provided classes, methods and call graph. The model takes… Read more

Working on a real case scenario in a five node Percona XtraDB Cluster (PXC), we were forced to use wsrep_sync_wait = 1, because the app does reads-after-write and we send reads to all the nodes. We had the idea to leave some nodes in DESYNC mode to reduce the flow control messages during peak load […]… Read more
