In our last post, we looked into the lifecycle of applications in Kubernetes. We see that Kubernetes doesn’t handle database backups itself. This is where Kubernetes Operators come into action. They add additional functions to Kubernetes, enabling it to set up, configure, and manage complex applications like databases within a Kubernetes environment for the user.In […]

This post was originally published on the Percona Community blog.If you are in the world of application development, you know that every application has a lifecycle. An application lifecycle refers to the stages that our application goes through, from initial planning, building, deployment, monitoring, and maintenance in different environments where our application can be executed.On […]

In my previous article, Comparisons of Proxies for MySQL, I showed how MySQL Router was the lesser performing Proxy in the comparison. From that time to now, we had several MySQL releases and, of course, also some new MySQL Router ones.Most importantly, we also had MySQL Router going back to being a level 7 proxy […]

Managing database servers involves different aspects, among which security is critical. We know that we should always grant the minimal required permissions to the different user accounts in the database, as having a user with high-level permission can lead to unexpected results, such as having an index drop affecting the system performance or even more […]

We’re happy to introduce Audit Log Filter — our newly upgraded audit plugin. Its functionality has been significantly improved in comparison to Audit Log and currently mirrors the functionality of the MySQL Enterprise Audit plugin. Starting with Percona Server for MySQL 8.0.34-26, the Audit Log Filter is available in a technical preview mode. You’re welcome […]

In Percona Managed Services, we manage Percona for MySQL, Community MySQL, and MariaDB. Sometimes, the replica server might have replication errors, and the replica might be out of sync with the primary. In this case, we can use Percona Toolkit’s pt-table-checksum and pt-table-sync to check the data drift between primary and replica servers and make […]

In this article, we will demonstrate how to achieve asynchronous replication automatic source failover when our replica is a Percona Server for MySQL (PS) and the source is a Percona XtraDB Cluster (PXC) cluster, using virtual IP (VIP) managed by Keepalived.Let us consider our architecture below with async replication from PXC to Percona Server for […]

Ensuring the security and resilience of your data hinges on having a robust backup strategy, and Percona XtraBackup (PXB), our open source backup solution for all versions of MySQL, is designed to make backups a seamless procedure without disrupting the performance of your server in a production environment.When combined with the versatility of Docker containers, […]

With the release of Percona XtraBackup 8.0.34-39, Percona XtraBackup (PXB) allows a backup on server version 8.0.35 and higher. We have removed the server version check because the MySQL 8.0 series has transitioned to bug fixes.A feature change in the MySQL 8.0 series, such as the redo log record structure, could cause PXB to fail […]

This blog was originally published in January 2021 and updated in November of 2023.As businesses and applications increasingly rely on MySQL databases to manage their critical data, ensuring data reliability and availability becomes paramount. In this age of digital information, robust backup and recovery strategies are the pillars on which the stability of applications stands. […]
