As we know different storage engines in MySQL have different file structures. Every table in MySQL 5.6 must have a .frm file in the database directory matching the table name. But where the rest of the data resides depends on the storage engine. For MyISAM we have .MYI and .MYD files in the database directory […]
In my previous post I pointed out that the existing ARCHIVE storage engine in MySQL may not be the one that will satisfy your needs when it comes to effectively storing large and/or old data. But are there any good alternatives? As the primary purpose of this engine is to store rarely accessed data in disk […]
(This is a cross post from percona.tv – the home of percona material in video form.) Last month I gave a presentation at the PHP UK Conference on the InnoDB storage engine.Â I was a last minute speaker, and I want to thank them for the time-slot and their hospitality at short notice.

However recently we got too busy with serving out customers and the backlog of things to take a look and write about is just growing larger and larger. So we decided […]
MySQL Users Conference 2008 has number of Storage Engines presented which claim to Kick Ass. Walking in exhibition hall you could see KickFire, Infobright, Tokutek, ScaleDB. I have not seen NitroDB in the exhibition call this year but they are also worth to mention. It is interesting to see all of them showing benchmarks with […]
I finally found a time to publish Landscape of Transactional Storage Engines slides on MySQL Presentations page , this is the talk which we gave on OSCON 2007 and which talks about current state behavior and performance properties of Innodb, Falcon, PBXT and SolidDB Storage Engines.
I promised to write little articles about all storage engines which sessions I attended during MySQL Users Conference but I did not get too far yet, too busy. So today it is time for PBXT. I was very interested about session about PBXT because this is storage engine does not target the same general purpose […]
