In this post, I will point you to Docker images for MySQL Group Replication testing. There is a new release of MySQL Group Replication plugin for MySQL 5.7.14. It’s a “beta” plugin and it is probably the last (or at lease one of the final pre-release packages) before Group Replication goes GA (during Oracle OpenWorld […]
Read MoreIn this post, I’ll review Docker multi-host network performance. In a past post, I tested Docker network. The MySQL Server team provided their own results, which are in line with my observations. For this set of tests, I wanted to focus more on Docker networking using multiple hosts. Mostly because when we set up a high availability […]
Read MoreIn this post, we’ll discuss Docker automatic MySQL slave propagation for help with scaling. In my previous posts on the Docker environment, I covered Percona XtraDB Cluster. Percona XtraDB Cluster can automatically scale by conveniently adding new nodes using the highly automated State Snapshot Transfer. State Snapshot Transfer allows a new node to copy data […]
Read MoreThis post will discuss how to get RocksDB from Docker containers to use with Percona Server for MongoDB. With our Percona Server for MongoDB 3.2 release, we made RocksDB a first class citizen. With this newly-available engine, we want to make it easy for everybody interested to try it. So it is now available in docker […]

The afternoon sessions at Percona Live 2016 are just as intriguing as the morning sessions. I’m trying to hit as many as I can, especially talks on interesting and upcoming technologies that are improving deployments and manageability. One of the talks I saw in this vein was MySQL and Docker Strategies, given by Patrick Galbraith, Senior Systems Engineer […]

In this blog post, we’ll discuss some of the basics regarding Docker MySQL replication. Docker has gained widespread popularity in recent years as a lightweight alternative to virtualization. It is ideal for building virtual development and testing environments. The solution is flexible and seamlessly integrates with popular CI tools. This post walks through the setup of MySQL […]
Read MoreThis will be another post on using Percona Server via a Docker image. I want to follow up on my previous post regarding CPU/Network overhead in Docker “Measuring Percona Server Docker CPU/network overhead” by measuring if there is any docker IO overhead on operations. After running several tests, it appears (spoiler alert) that there is no Docker IO overhead. […]
Read MoreNow that we have our Percona Server Docker images, I wanted to measure the performance overhead when we run the database in the container. Since Docker promises to use a lightweight container, in theory there should be very light overhead. We need to verify that claim, however. In this post I will show the numbers for CPU and network intensive workloads, […]
Read MoreDocker is incredibly popular tool for deploying software, so we decided to provide a Percona Docker image for both Percona Server MySQL and Percona Server for MongoDB. We want to create an easy way to try our products. There are actually some images available from https://hub.docker.com/_/percona/, but these images are provided by Docker itself, not from Percona. […]
Read MoreEven with software like Percona Xtrabackup, logical backups remain an important component of a thorough backup strategy. To gather a logical backup in a timely fashion we rely on a tool called mydumper. In the Percona Managed Services department we’re lucky enough to have one of the project’s most active contributors and many of the latest features and […]
