We’re moving along on the first day at Percona Live Data Performance Conference 2016, and I was able to attend a lecture from Intel’s Ken LeTourneau on Performance of Percona Server for MySQL on Intel Server Systems using HDD, SATA SSD, and NVMe SSD as Different Storage Mediums. In this talk, Ken reviewed some benchmark testing he did using MySQL on various types of storage mediums. This talk looked at the performance of Percona Server for MySQL for Linux running on the same Intel system, but with three different storage configurations. We looked at and compared the performance of:

1. a RAID of HDD
2. a RAID of SATA SSD
3. a RAID of NVMe SSD

In the talk,  Ken covered the hardware and system …

I was recently talking on the #mariadb channel on FreeNode and I got a question about the often overlooked PDF documentation generation. In this blog I will show how to create a set of PDF files of the MariaDB MaxScale's documentation - a good way to keep the documentation handy. I did this on Ubuntu 14.04, but it should also work on other platforms.

Installing Packages

Since we'll be configuring MariaDB MaxScale, we'll need to install a few dependencies for MariaDB MaxScale and also grab the MariaDB server tarball. We start by installing the following packages.

sudo apt-get install git build-essential libssl-dev libaio-dev ncurses-dev bison flex cmake perl libtool libcurl4-openssl-dev libpcre3-dev tcl tcl-dev

Then we'll get the MariaDB server tarball which contains all the required parts for MariaDB MaxScale and extract it into our home directory.

wget …

Today the first MariaDB 10.2 alpha popped up and for the first time there is support for window functions.

I'll describe what's been announced, what's been expected, comparisons to other DBMSs, problems (including crashes and wrong answers), how to prepare, what you can use as a substitute while you wait.

I assume some knowledge of what window functions are. If you'd prefer an introductory tutorial, I'd suggest reading articles like this one by Joe Celko before you continue reading this post.

Percona is excited to announce the launch of Percona Monitoring and Management Beta!

Percona Monitoring and Management (PMM) is a fully open source solution for both managing MySQL platform performance and tuning query performance. It allows DBAs and application developers to optimize the performance of the Database Layer. PMM is an on-premises solution that keeps all of your performance and query data inside the confines of your environment, with no requirement for any data to cross the internet.

Assembled from a supported package of “best of breed” open source tools such as Prometheus, Grafana and Percona’s Query Analytics, PMM delivers results right out of the box.

With PMM, anyone with database maintenance responsibilities can get more visibility for actionable enhancements, realize faster issue resolution times, …

The MaxScale persistent connection feature has been available since version 1.3.0. It aims to reduce the load on the database servers in specific scenarios. Testing indicates benefits and feedback from live use has been positive.

A typical scenario where benefits will be obtained is a PHP web server application that uses a group of MariaDB databases to store information. HTTP is well known to be a connectionless protocol, and so each request from a browser is usually handled as a single invocation of a PHP program, which makes a fresh database connection and terminates it on completion. This is likely to happen in well under a second, many times per second. There are thus many instances of the relatively expensive operation of making a new database connection.

You might think that the obvious way to reduce this load is to use PHP persistent connections. But for a variety of technical …
