Database backups are a fundamental requirement in almost every implementation, no matter the size of the company or the nature of the application. Taking a backup should be a simple task that can be automated to ensure it’s done consistently and on schedule. Percona has an enterprise-grade backup tool, Percona XtraBackup, that can be used to accomplish these tasks. Percona also has a Percona Kubernetes Operator for Percona XtraDB Cluster (PXC Operator), which has Percona XtraBackup built into it. Percona XtraBackup has the ability for both automated and on-demand backups. Today we will explore taking backups and restoring these backups using the PXC Operator deployed …

As a Solutions Engineer at Percona, one of my responsibilities is to support our customers as they investigate new and emerging technologies. This affords me the opportunity to speak to many current and new customers who partner with Percona.

The topic of Kubernetes is becoming more popular as companies are investigating and adopting this technology. The issue most companies are encountering is having a stateful database that doesn’t fall victim to an environment tuned for ephemeral workloads. This obviously introduces a level of complexity as to how to run a stateful database in an inherently stateless world, as databases are not natively designed for that.

To make your life easier, as a part of the Percona Cloud-Native Autonomous Database Initiative, our engineering teams have built a …

This release, based on Percona Server for MySQL 8.0 and Galera 4, brings together the best features of these and other products to deliver an open-source high availability MySQL solution that helps enterprises minimize unexpected downtime and data loss, improve data security, and ensure data integrity of your database environments supporting your critical business applications in the most demanding public, private, and hybrid cloud environments.

Percona XtraDB Cluster 8.0 enables enterprises to improve data security and ensure data integrity with new encryption and streaming replication features. …

During this joint webinar our speakers, Alkin Tezuysal, Technical Expert at Percona and Sugu Sougoumarane, Co-Founder and CTO at PlanetScale, will provide attendees with hands-on experience using Vitess using Kubernetes. They will start by providing a quick overview of Vitess – including key concepts and terminology, and then describe the deployment options for both in Kubernetes.

The hands-on exercises will cover many of the key workflows with running a sharded system:

– Moving from an unsharded system to a vertical split one (moving some tables to a different host)
– Sharding large tables across several instances
– Backups, Recoveries, and failovers (both planned and unplanned).

Attendees are not expected to have any prior experience with Vitess but will find it useful if they have prior experience completing these tasks in a MySQL environment and general know-how …

As our Percona Kubernetes Operator for Percona XtraDB Cluster gains in popularity, I am getting questions about its performance and how to measure it properly. Sysbench is the most popular tool for database performance evaluation, so let’s review how we can use it with Percona XtraDB Cluster Operator.

Operator Setup

I will assume that you have an operator running (if not, this is the topic for a different post). We have the documentation on how to get it going, and we will start a three-node cluster using the following cr.yaml file:

apiVersion: pxc.percona.com/v1-3-0
kind: PerconaXtraDBCluster
metadata:
  name: cluster1
  finalizers:
    - delete-pxc-pods-in-order
spec:
  secretsName: my-cluster-secrets
  sslSecretName: …

In this blog post, I’d like to share some experiences in setting up a Vitess environment for local tests and development on OSX/macOS. As previously, I have presented How To Test and Deploy Kubernetes Operator for MySQL(PXC) in OSX/macOS, this time I will be showing how to Run Vitess on Kubernetes.

Since running Kubernetes on a laptop is only experimental, I had faced several issues going through straight forward installation steps so I had to apply a few workarounds to the environment. This setup will have only minimum customization involved.

For a high-level overview of Vitess, please visit Part I of this series, …

In this blog post series, we will discuss an overview of Vitess technology. Vitess is a database clustering solution for horizontal scaling of data sets currently suitable to 250Gb – 300Gb in sizes*. It’s a proven technology used by several web-scale companies including YouTube. PlanetScale is the company behind developing and supporting this open-sourced project. 

Introduction to Vitess 

Here’s high-level Vitess architecture visually explained. 

Ref: Sugu Sougoumarane presents an overview of Vitess at Highload in Moscow.

Basic Vitess Components

There are two main components of Vitess. One of them is vtgate which works as a query router where vttablet is a proxy to MySQL to serve the data.

We are glad to announce the 1.2.0 release of the  Percona Kubernetes Operator for Percona XtraDB Cluster.

The Percona Kubernetes Operator for Percona XtraDB Cluster automates the lifecycle and provides a consistent Percona XtraDB Cluster instance. The Operator can be used to create a Percona XtraDB Cluster, or scale an existing Cluster, and contains the necessary Kubernetes settings.

The Operator simplifies the deployment and management of the Percona XtraDB Cluster in Kubernetes-based environments. It extends the Kubernetes API with a new custom resource for deploying, configuring and managing the application through the whole life cycle.

The Operator source code is available …

The PingCAP team has always been a strong supporter of Percona and the wider open source database community. As the people who work day in and day out on TiDB, an open source NewSQL database with MySQL compatibility, open source database is what gets us in the morning, and there’s no better place to share that passion than Percona Live.

At this year’s Percona Live Open Source Database Conference in Austin, Texas, we are particularly excited to bring you a full track of talks and demo on the latest development in TiDB during Day 1 of the conference.

Who would benefit from the TiDB track

The TiDB track is designed to share with developers, DBAs, and practitioners in general technical know-hows, reproducible benchmarks (no benchmark-eting), and best practices on how TiDB can solve their problems. …

Kubernetes Operators are amazing and they are already playing an important role for those who are managing large scale applications. I personally think that we will manage all applications using Operators.

In this tutorial I will show you how to setup a MySQL cluster using the MySQL Operator on Kubernetes.

Prerequisites:

1. Install kubectl
2. Install Helm
3. Kubernetes Cluster: Use minikube locally or check out Luca’s post on how to set up OKE.

Let’s start with cloning the MySQL repository which contains the …
