2022 was an exciting year for Percona Monitoring and Management (PMM). We’ve added and improved many features, including Alerting and Backup Management. These updates are designed to keep databases running at peak performance and simplify database operations. But as companies grow and see more demand for their databases, we need to ensure that PMM also remains scalable so you don’t need to worry about its performance while tending to the rest of your environment.

PMM2 uses VictoriaMetrics (VM) as its metrics storage engine. Percona’s co-Founder Peter Zaitsev wrote a detailed post about migration from Prometheus to VictoriaMetrics, One of the most significant differences in …

Let’s look at how you can run Percona databases on Kubernetes, the easy way.

Chances are that if you are using the latest Percona Monitoring and Management (PMM) version, you have seen the availability of the new Percona Database as a Service (DBaaS). If not, go and get a glimpse of the fantastic feature with our docs on DBaaS – Percona Monitoring and Management.

Now, if you like it and wanna give it a try! (Yay!), but you don’t wanna deal with Kubernetes, (nay)o worries; we have a tool for you. Introducing the Percona DBaaS Infrastructure Creator, or Percona My Database as a Service (MyDBaaS).

When we need to upgrade from MySQL 5.7 to MySQL 8, we could choose to do an in-place upgrade or set up another MySQL 8 server(s) from the existing running MySQL 5.7 replica.

This article will explain how to set up MySQL 8 as a replica from an existing MySQL 5.7 server with Percona XtraBackup.

In my lab, we have two test nodes:

PRIMARY:  mysql57 (192.168.56.111)    with   Percona Server 5.7 and  xtrabackup 2.4 installed
REPLICA:  mysql8    (192.168.56.113)   with  Percona Server 8  and   xtrabackup 8.0 installed

0. Pre-flight check with MySQL upgrade checker utility

Let’s run the MySQL upgrade checker utility to verify whether MySQL 5.7 server instances are ready for an upgrade.

MySQL  localhost  JS > util.checkForServerUpgrade('root@localhost:3306', {"password":"####", …

For a long time, I never encountered any system using FEDERATED tables. But recently, there seems to be more interest for FEDERATED tables. Is this related to the increase of microservices? In a microservices architecture, services are typically designed to be small, loosely coupled, and independently deployable. Each service may have its own database, which […]

InnoDB has been the default storage engine for MySQL since version 5.5 (July 2010!). If you are still using MyISAM as the storage engine for your tables, it might be time to consider migrating to InnoDB. InnoDB offers several advantages over MyISAM: <!– wp:list {"className":"","epStylingOptions":{"columnsResponsiveEnabled":false,"columnsHoverEnabled":false,"itemsSpacingResponsiveEnabled":false,"itemsSpacingHoverEnabled":false,"listStyleResponsiveEnabled":false,"listStyleHoverEnabled":false,"listIconResponsiveEnabled":false,"listIconHoverEnabled":false,"columns":{"target":"","responsive":true,"hover":true,"options":[{"custom":true,"control":"ToggleOptions"},{"label":"Columns","control":"Range","attribute":"columns","css":"grid-template-columns","customValue":"repeat({{value}}, …

MySQL uses Redo Logs internally during crash recovery to correct data written by incomplete transactions. But how do you know what the right Redo Log size is? We will walk through how to figure that out in this blog.

We already have a couple of posts related to this topic. “How to calculate a good InnoDB log file size” and “How to Choose the MySQL innodb_log_file_size.” The first one has the formula I’ll mention in this blog, and the second has more details regarding Redo Logs. Most of it is still valid, just replace innodb_log_file_size / innodb_log_files_in_group with innodb_redo_log_capacity.

So in this one, I want to focus on two things:
