In part one and part two of this series, we introduced the different ways to manage MySQL configurations and precedence when using the Percona XtraDB Cluster (PXC) object and ConfigMap. In this post, we will see the precedence when secrets are used for MySQL configurations in Percona Operator for MySQL based on Percona XtraDB Cluster.

CASE-4: Secret with name cluster1-pxc and ConfigMap with name cluster1-pxc but without configuration in PXC object

When the MySQL configuration is present in the ConfigMap and secret but not in the PXC …

In part one of this series, we introduced the different ways to manage MySQL configurations. In this post, we will walk through different possibilities and the changes happening while modifying MySQL configurations with the operator.

Percona Distribution for MySQL Operator based on Percona XtraDB Cluster (PXC) provides three ways for managing MySQL, but the question is, what is the precedence among options? We will walk through several cases of using MySQL configs. For the sake of simplicity, we will play with the values of the Galera cache to see the effects.

During the last 20 years MySQL has democratized the usage of transactional databases.
Now with MySQL HeatWave we are in the process of democratizing Analytics and Machine Learning.

With MySQL HeatWave,
valorizing your data has never been so easy!

In this article I will show you how easy it is to use the Machine Learning capabilities of MySQL HeatWave. We will use the famous Iris dataset and we’re going to build, train, deploy and explain a machine learning model within MySQL HeatWave using Apache Zeppelin.

The post Iris Data Set with MySQL HeatWave Machine Learning & Zeppelin first appeared on dasini.net - Diary of a MySQL expert.

In this blog post, I will show how to install the MySQL-compatible Percona XtraDB Cluster (PXC) Operator on Minikube as well as perform some basic actions.   I am by no means a Kubernetes expert and this blog post is the result of my explorations preparing for a local MySQL Meetup, so if you have some comments or suggestions on how to do things better, please comment away!

For my experiments, I used Minikube version 1.26 with the docker driver in the most basic installation on Ubuntu 22.04 LTS, though it should work with other combinations, too. You also can find the official “Running Percona XtraDB Cluster on Minikube” documentation …

There are two Operators at Percona to deploy MySQL on Kubernetes:

• one is based on Percona XtraDB Cluster (PXC), production-ready and widely adopted
• another is based on Percona Server for MySQL, now in tech preview and not recommended for production yet

We wrote a blog post in the past explaining the thought process and reasoning behind creating the new Operator for MySQL. The goal for us is to provide production-grade solutions to run MySQL in Kubernetes and support various replication configurations:

• Synchronous replication

Percona Server for MySQL 8.0.28-20 introduces a new keyring component, component_keyring_kms, which allows using the AWS Key Management Service as a keyring. The component is also included in Percona XtraBackup 8.0.28, allowing backing up databases encrypted with this component.

The feature is similar to the AWS keyring plugin included in MySQL Enterprise, but it is implemented as a component instead, and because of that, it requires a different configuration.

Configuring AWS KMS

The component uses a single Master Key on KMS, which has to be created manually before configuring the component. This key can also be changed later, and existing keys using the old key will remain usable, as long as the key still exists …
