Docker automatic MySQL slave propagation

In 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 […]

Measuring Docker IO overhead

Docker

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 on operations. After running several tests, it appears (spoiler alert) that there is no Docker IO overhead. […]

Measuring Percona Server Docker CPU/network overhead

 | February 5, 2016 |  Posted In: MySQL, Percona Server

Docker

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 claim, however. In this post I will show the numbers for CPU and network intensive workloads, […]

Using Cgroups to Limit MySQL and MongoDB memory usage

 | July 1, 2015 |  Posted In: InnoDB, MongoDB, MySQL

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 servers with the usually high amount of memory (128GB or more), but I am […]

Playing with Percona XtraDB Cluster in Docker

 | June 30, 2015 |  Posted In: High-availability, MySQL, Percona XtraDB Cluster, Quality Assurance, XtraDB Cluster

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 also the MySQL Sandbox which can be used for the same […]
