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...

In 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...

In this post, we’ll look at scaling Percona XtraDB Cluster with ProxySQL in Docker Swarm. In my previous post, I showed how to employ Percona XtraDB Cluster on multiple nodes in a Docker network. The intention is to be able to start/stop nodes and...

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 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...

Now 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...

Docker 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...

Quite often, especially for benchmarks, I am trying to limit available memory for a database server (usually for MySQL, but recently for MongoDB also). This is usually needed to test database performance in scenarios with different memory limits. I have physical...

Like any good, thus lazy, engineer I don’t like to start things manually. Creating directories, configuration files, specify paths, ports via command line is too boring. I wrote already how I survive in case when I need to start MySQL server (here). There is...
