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.

Nowadays it is more complex. We have several different makers of our favourite database management system: Oracle/MySQL, Monty Program AB and Percona with their products: MySQL, MariaDB and Percona Server.

Introduction

At the DOAG 2010 we found that there are already a lot of Plugins etc. for MySQL available. Therefor it will be a good time to start with a collection of Plugins, UDF's etc. available.

Because we have done already a collection of MySQL Storage Engines earlier please look there form more information.

A little summary about the MySQL CSV table engine:

• The SQL-Demo script (930 byte) for the following article.
• The CSV converter to convert normal CSV files into a CSV format which is for MySQL acceptable.

Caution: Use on your own risk!

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...

If you need some help deciding which is the right Storage Engine or even strategy for you or if you want us to make an independent and vendor neutral comparison of those Storage Engines consider our FromDual Consulting Services!

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.
