MySQL and Openstack deep dive
14 April 11:30am - 12:20pm @ Room 204
50 minutes conference
Like it or leave it, there's no disputing that MySQL is by far the most commonly used database in OpenStack deployments. Most folks know that there are a number of different flavors of MySQL -- standard MySQL, MariaDb, Percona XtraDb, MySQL Galera, Percona XtraDb Cluster, etc. However, there are a number of misconceptions and myths around the pros and cons of these flavors of MySQL. In this talk, we hope to dispel some of these myths and give some clear information on what are the strengths and weaknesses of each of these flavors, what pitfalls to avoid when migrating between them, and what architectural information to take into account when planning your OpenStack MySQL database deployments. We will discuss replication topologies and techniques, and explain how the Galera Cluster variants differ from standard MySQL replication. Finally, in the latter part of the session, we do a deep dive into MySQL database performance analysis. We will be analyzing the results of a Rally run showing a typical Nova workload, and demonstrate using pt-query-digest to determine if a synchronously-replication database cluster like Percona XtraDb Cluster is a good fit for certain OpenStack projects.
