So you want to contribute to OpenStack? I can help!

For the last year or so I have been involved with OpenStack and more specifically the Trove (DBaaS) project as sort of an ambassador for Percona, contributing bits of knowledge, help and debugging wherever I could and thought I would share some of my experience with others that wanted to get involved with OpenStack development, documentation, testing, etc. Getting started with OpenStack contributions is also the idea behind my talk next month at …

Introducing ‘MySQL 101,’ a 2-day intensive educational track at Percona Live this April 15-16
+0 Vote Up -0Vote Down

Talking with Percona Live attendees last year I heard a couple of common themes. First, people told me that there is a lot of great advanced content at Percona Live but there is not much for people just starting to learn the ropes with MySQL. Second, they would like us to find a way to make such basic content less expensive.

I’m pleased to say we’re able to accommodate both of these wishes this year at Percona Live! We have created a two-day intensive track called “MySQL 101” that runs April 15-16. MySQL …

How to Deploy High Availability CloudStack/CloudPlatform with MariaDB Galera Cluster
+0 Vote Up -0Vote Down

Apache CloudStack is a turnkey orchestration platform to deliver IaaS clouds. As a cloud infrastructure scales to hundreds or thousands of servers, with production environments supporting multiple applications and services, high availability becomes a key requirement. Just as for OpenStack, it is possible to deploy the CloudStack management server in a multi-node installation. Since the management server uses a MySQL database to store the state of all its objects, the database could …

Understanding reservations, concurrency, and locking in Nova
+0 Vote Up -0Vote Down

Imagine that two colleagues, Alice and Bob, issue a command to launch a new virtual machine at approximately the same moment in time. Both Alice’s and Bob’s virtual machines must be given an IP address within the range of IP addresses granted to their project. Let’s say that range is 192.168.20.0/28, which would allow for a total of 16 IP addresses for virtual machines [1]. At some point during the launch sequence of these instances, Nova must assign one of those addresses to each virtual machine.

How do we prevent Nova from assigning the same …

It does not matter if Aurora performs 1x or 10x MySQL: it _is_ a big thing
+1 Vote Up -0Vote Down

I spent the last 4 years at SkySQL/MariaDB working on versions of MySQL that could be “suitable for the cloud”. I strongly believed that the world needed a version of MySQL that could work in the cloud even better than its comparable version on bare metal. Users and administrators wanted to benefit from the use of cloud infrastructures and at the same time they wanted to achieve the same performance and overall stability of their installations on bare metal. Unfortunately, ACID-compliant databases in the cloud suffer from the issues that any centrally controlled and strictly persistent system can get when hosted on highly distributed and …

Schema changes in MySQL for OpenStack Trove users
+0 Vote Up -0Vote Down

People using OpenStack Trove instances can hit a common issue in the MySQL world: how to perform schema change operations while minimizing the impact on the database server? Let’s explore the options that can allow online schema changes.

Summary

With MySQL 5.5, pt-online-schema-change from Percona Toolkit is your best option for large tables while regular ALTER TABLE statements are only acceptable for small tables. Also beware of metadata locks.

With MySQL 5.6, almost all types of …

Backup and restore of MySQL to OpenStack Swift
+0 Vote Up -0Vote Down

MySQL database usage is popular in OpenStack. Core OpenStack services for Compute (Nova), Storage (Cinder), Neutron (Networking), Image (Glance) and Identity (Keystone) all use MySQL database.

MySQL – as the world’s most popular database, runs inside OpenStack Virtual Machines and serves as database backend to OpenStack cloud based applications. The MySQL instances can be configured to run in virtual machines manually (by simply installing MySQL inside a VM and running it) or can be created in an on-demand fashion by OpenStack Database-as-a-Service (Trove).

In either case, the MySQL data is …
