Switching from MySQL/MyISAM to Galera Cluster requires that all tables (except those from the mysql, information_schema and performance_schema) are using the InnoDB Storage Engine.

How can I find what InnoDB version I am using?

In the old days everything was simpler. We had one maker of our favourite database management system and possibly the choice between different Storage Engines. Mostly the decision has to be taken between MyISAM and InnoDB. When you care about your data integrity you have chosen InnoDB.

Introduction

In his presentation about PBXT at the DOAG Conference 2010 Paul McCullagh was speaking about memory resident PBXT tables. They will be available in version 1.1 of the PBXT Storage Engine Plugin. Memory resident PBXT tables should have similar characteristics like normal MySQL MEMORY</span> tables</a>. But in addition to the MEMORY tables they are transactional and can handle BLOB</span> and TEXT attributes.

What is a Federated Table?

A Federated Table is a table which points to a table in an other MySQL database instance (mostly on an other server). It can be seen as a view to this remote database table. Other RDBMS have similar concepts for example database links.

One of the big advantages of MySQL is its concept of Pluggable Storage Engines. This means you can choose the most optimal Storage Engine for your needs. This also has a disadvantage: You have to know what you are doing…

In a round-robin database (RRD) usually time-series data like network bandwidth, temperatures, CPU load etc. is stored. The data is stored in the way that system storage footprint remains constant over time. This avoids resource expensive purge jobs and reduces complexity.
