Rackspace doubling-down on open-source databases, Percona Server
+0 Vote Up -0Vote Down

Founded in 1998, Rackspace has evolved over the years to address the way customers are using data – and more specifically, databases. The San Antonio-based company is fueling the adoption of cloud computing among organizations large and small.

Today Rackspace is doubling down on open source database technologies. Why? Because that’s where the industry is heading, according to Sean Anderson, Manager of Data Services at Rackspace. The company, he said, created a separate business unit of 100+ employees focused solely on database workloads.

The key technologies under the hood include both relational databases (e.g., MySQL,

MySQL & OpenStack: How to overcome issues as your dataset grows
+0 Vote Up -0Vote Down

MySQL is the database of choice for most OpenStack components (Ceilometer is a notable exception). If you start with a small deployment, it will probably run like a charm. But as soon as the dataset grows, you will suddenly face several challenges. We will write a series of blog posts explaining the issues you may hit and how to overcome them.

Where is MySQL used in OpenStack?

Have a look at the logical diagram of OpenStack below (click the image for a larger view).

Percona Server and Percona XtraDB Cluster provide high-performance alternatives for MySQL users. We have also seen rapidly growing interest in these solutions in the OpenStack community where higher performance and high availability are crucial. Many OpenStack users are adopting these solutions but we’ve also seen demand from companies creating OpenStack distros. For example, Percona XtraDB Cluster is now

Speaking about libAttachSQL at Percona Live London
+0 Vote Up -0Vote Down
As many of you know I'm actively developing libAttachSQL and am rapidly heading towards the first beta release.  For those who don't, libAttachSQL is a lightweight C connector for MySQL servers with a non-blocking API.  I am developing it as part of my day job for HP's Advanced Technology Group.  It was in-part born out of my frustration when dealing with MySQL and eventlet in Python back when I was working on various Openstack projects.  But there are many reasons why this is a good thing for C/C++ applications as well.

What you may not know is I will be giving a talk about libAttachSQL, the technology behind it and the decisions we made to get here

OpenStack users shed light on Percona XtraDB Cluster deadlock issues
+0 Vote Up -0Vote Down

I was fortunate to attend an Ops discussion about databases at the OpenStack Summit Atlanta this past May as one of the panelists. The discussion was about deadlock issues OpenStack operators see with Percona XtraDB Cluster (of course this is applicable to any Galera-based solution). I asked to describe what they are seeing, and as it turned out, nova and neutron uses the SELECT … FOR UPDATE SQL construct quite heavily. This is a topic I thought was worth writing

Using sysbench 0.5 for performing MySQL benchmarks
+0 Vote Up -0Vote Down

Given the recent excitement & interest around OpenStack I wanted to make sure I was ready to conduct appropriate evaluations of system performance.  I generally turn to sysbench since it comes with a variety of different tests (accessed via –test= option interface), including:

  • fileio – File I/O test
  • cpu – CPU performance test
  • memory – Memory functions speed test
  • threads – Threads subsystem performance test
  • mutex – Mutex performance test

As you can see, sysbench lets you stress many of the fundamental components of your hardware and infrastructure, such as your disk subsystem, along with your CPUs and memory. An additional option exists that is designed to perform synthetic stress testing of MySQL, and I was surprised when I didn’t see it in the

OpenStack Trove Day 2014 Recap: MySQL and DBaaS

OpenStack Trove Day

I just returned from a week in Cambridge, Massachusetts where I was attending the OpenStack Trove Day and the Trove mid-cycle meetup, both sponsored by the great folks at Tesora.

I am relatively new to the OpenStack and Trove arenas so this was a fantastic opportunity for me to learn more about the communities, the various components within OpenStack, and what part Trove plays. I found the entire event very worthwhile – I met a lot of key people in the community, learned more about Trove and its potential, and in general felt a great energy and

OpenStack’s Trove: The benefits of this database as a service (DBaaS)
+0 Vote Up -0Vote Down

In a previous post, my colleague Dimitri Vanoverbeke discussed at a high level the concepts of database as a service (DBaaS), OpenStack and OpenStack’s implementation of a DBaaS, Trove. Today I’d like to delve a bit further into Trove and discuss where it fits in, and who benefits.

Just to recap, Trove is OpenStack’s implementation of a database as a service for its cloud infrastructure as a service (IaaS). And as the mission statement declares, the Trove project seeks to provide a scalable and reliable cloud database service providing functionality for both relational and non-relational database engines. With the current release of
