Migration between MySQL/Percona Server and MariaDB

This week, we did some migrations from MariaDB 10.0 to Percona Server 5.6 at the IT department of a big German bank.

We were perfectly aware that since version 10.0 the MariaDB code base started to diverge slightly away from the MySQL and Percona Server code base which are still pretty close to each other.

Because of the Percona Server option enforce_storage_engine we wanted to do this migration.

Backup and Recovery Manager for MySQL, MariaDB and Percona Server (fromdual_brman)

About

The FromDual Backup and Recovery Manager for MySQL and MariaDB(fromdual_brman) is a wrapper script for standard MySQL backup tools. The Problem with MySQL backup tools is, that they have many options and thus are overcomplicated and errors are easy made.

fromdual_bman has the intention to make backups for MySQL easier and technically correct. This means it should per default not allow non-consistent backups or complain if some functions or parameters are used in the wrong way to guarantee proper backups.

FromDual Performance Monitor for MySQL 0.9.2 has been released

FromDual has the pleasure to announce the release of the new version 0.9.2 of its popular Database Performance Monitor for MySQL, MariaDB and Percona Server mpm.

MySQL single query performance - the truth!

MySQL single query performance - the truth!

As suggested by morgo I did a little test for the same query and the same data-set mentioned in Impact of column types on MySQL JOIN performance but looking into an other dimension: the time (aka MySQL versions).

The answer

To make it short. As a good consultant the answer must be: "It depends!" :-)

Impact of column types on MySQL JOIN performance

Taxonomy upgrade extras: 

In our MySQL trainings and consulting engagements we tell our customers always to use the smallest possible data type to get better query performance. Especially for the JOIN columns.
