MySQL 8.0 all new Error Logging

MySQL error log contains diagnostics messages such as errors, warnings and notes that occur during MySQL startup, shutdown and while the server is running. For example, a InnoDB table is corrupted and need to repaired, This will be recorded in the error log. MySQL 8.0 Error uses the MySQL component architecture for log event filtering and writing. The MySQL system variable log_error_services controls which log components to enable and the rules for filtering the log events. The component table in the mysql system database contains the information about currently loaded comments and shows which components have been registered with INSTALL COMPONENT. To confirm the components installed, you may use the SQL below:

MySQL and PHP Basics Part I

I have had some requests to write some blogs on the basics of using PHP and MySQL together.  This will not be a series for the experienced as it will start at a level where I will go into a lot of details but expect very few prerequisites from the reader.  If this is not you, please move on. If it is you and you read something you do not understand, please contact me to show me where I assumed too much.

PHP and MySQL are both in their mid twenties and both vital in the worlds of developers.  With the big improvements in PHP 7 and MySQL 8, I have found a lot of developers flocking to both but stymied by the examples they see as their are many details not explained. So let's get to the explaining!
1. Use the latest software
If you are not using PHP 7.2 or 7.3 (or maybe 7.1) then you are missing out in features and performance.  The PHP 5.x series is deprecated, no longer support, and …

dbdeployer community - Part 2: Percona XtraDB Cluster

This was not on the radar. I have never been proficient in Galera clusters and related technologies, and thus I hadn’t given much thought to Percona Xtradb Cluster (PXC), until Alkin approached me at FOSDEM, and proposed to extend dbdeployer features to support PXC. He mentioned that many support engineers at Percona use dbdeployer) on a daily basis and that the addition of PXC would be welcome.

I could not follow up …

Reducing High CPU on MySQL: a Case Study

In this blog post, I want to share a case we worked on a few days ago. I’ll show you how we approached the resolution of a MySQL performance issue and used Percona Monitoring and Management PMM to support troubleshooting. The customer had noticed a linear high CPU usage in one of their MySQL instances and was not able to figure out why as there was no much traffic hitting the app. We needed to reduce the high CPU usage on MySQL. The server is a small instance:

Models | 6xIntel(R) Xeon(R) CPU E5-2430 0 @ 2.20GHz
10GB RAM

This symptom can be caused by various different reasons. Let’s see how PMM can be used to troubleshoot the issue.

CPU

It’s important to understand where the CPU time is being consumed: user space, system space, iowait, and so on. Here we can see that CPU usage was …

How to Upgrade Amazon Aurora MySQL from 5.6 to 5.7

Over time, software evolves and it is important to stay up to date if you want to benefit from new features and performance improvements.  Database engines follow the exact same logic and providers are always careful to provide an easy upgrade path. With MySQL, the mysql_upgrade tool serves that purpose.

A database upgrade process becomes more challenging in a managed environment like AWS RDS where you don’t have shell access to the database host and don’t have access to the SUPER MySQL privilege. This post is a collaboration between Fattmerchant and Percona following an engagement focused on the upgrade of the Fattmerchant database from Amazon Aurora MySQL 5.6 to Amazon Aurora MySQL 5.7. Jacques Fu, the CTO of Fattmerchant, is the co-author of this post.  Our initial plan was to follow a path laid out previously by others but we had difficulties finding any …
