I personally like PCIe based Flash, but from a pricing point our customers are looking for cheaper alternatives. SATA SSD is an options. There is many products based on MLC technology, and Intel 320 I would say is the most popular. I do not particularly like its write performance – I wrote about it before, […]
I wrote about Galera about 1.5 years ago: State of the art: Galera – synchronous replication for InnoDB. It was about the 0.7 release, which was more like a proof-of-concept release (though Galera’s developers may not agree with that ) with some serious limitations (like using mysqldump for node propagation). The Galera team heard my […]
Percona, and Yasufumi Kinoshita who works for Percona, received two awards from the O’Reilly MySQL Conference co-chairs on behalf of the committee that voted on the nominees. The awards were: to Yasufumi as O’Reilly MySQL Community Contributor of the Year 2011 for InnoDB performance improvements, and to XtraBackup as O’Reilly MySQL Application of the Year […]
You probably saw the Twitter storm over Oracle’s pricing changes and InnoDB in the last few days. The fear about Oracle removing InnoDB from the free version of MySQL was baseless — it was just a misunderstanding. Still, in the years since MySQL has been acquired by Sun, and then by Oracle, many MySQL users […]
Now that O’Reilly has announced they’re going to have a MySQL conference independently of Sun/MySQL, we have decided not to proceed with plans for our own Performance Conference. We are participating in the O’Reilly conference, and we will do everything possible to make that a great success for everyone. See you there!
As my first contribution to the MySQL Performance Blog, I joined Percona at the beginning September, I chose to cover the various high-availability (HA) options available for MySQL.Â I have done dozen of MySQL HA related engagements while working for Sun/MySQL over the last couple of years using Heartbeat, DRBD and NDB cluster and I’ll […]
MySQL 5.4 comes with Innodb engine which seems to have much better performance than MySQL 5.0 – this is due to locking and IO patches from Google integrated in this release (which are similar to appropriate Percona patches) as well as some unique fixes such as different innodb_thread_concurrency handling and other optimization. Should we take […]
The 2009 Percona Performance Conference finished up last week, and was overall a resounding success. Thanks to all of the speakers, O’Reilly, and Sun/MySQL for help making it happen! Most slides have been uploaded; look for the stragglers over the next couple of days.
So a while ago I wrote about fun post about MySQL Scalability to 256 way…. Besides discussion on the thread itself I had a lot of private comments in my mail from Sun/MySQL employees which tended to agree with me on this being the a large stretch.
