I will be attending the DrupalCON Denver Conference  next week.

Come visit Oracle Booth #400 and find out the latest information about MySQL and Linux!  I will be at the booth so please stop by and say hello. I believe you will have a chance to win a Kindle as well.


More related information can be found via my previous blog post.

In the yet to be released MySQL 5.6.6 DMR, there has been a change to the restriction of just one TIMESTAMP column with the DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP syntax. It is now possible for any TIMESTAMP to have either column defintion.

Just a reminder that I will be giving a talk “Percona XtraDB Cluster” on coming San Francisco MySQL Meetup, next Wednesday, March-21, 2012. Along with talk I will give away one full ticket (tutorials + sessions + expo hall) to Percona Live MySQL User Conference 2012 and three copies our new book “High Performance MySQL, 3rd edition”. Well, I hope I will have printed copies at that time; if not, I will give away promises to send printed copies to winners as soon as I have them.
If you are in SF Bay are, I hope to see you on meetup.

Mark Cuban is no fool. A tech billionaire, the no-nonsense owner of the Dallas Mavericks is just the sort of person you'd expect to value software patents. So the title of his blog post this Tuesday, "I hope Yahoo crushes Facebook in its patent suit," may not look out of place to you.

As ext4 is a standard de facto filesystem for many modern Linux system, I am getting a lot of question if this is good for SSD, or something else (i.e. xfs) should be used.
Traditionally our recommendation is xfs, and it comes to known problem in ext3, where IO gets serialized per i_node in O_DIRECT mode (check for example Domas’s post)

However from the results of my recent benchmarks I felt that this should be revisited.
While I am still running experiments, I would like to share earlier results what I have.

I use STEC SSD drive 200GB SLC SATA (my thanks to STEC for providing drives).

What I see, that ext4 still has problem with O_DIRECT. There are results for “single file” with O_DIRECT case (sysbench fileio 16 KiB blocksize random write workload):

The Schooner performance team completed a report that documents a TPCC-mysql benchmark run at the scale of 5000 warehouses (about 500GB) to observe stability at high levels of throughput. The impetus for this run was a Clustrix (a Flash-memory storage based database appliance) report documenting the solution’s stability and scalability at 3, 6 and 9 cluster nodes using the same benchmark and at the same scale.
SchoonerSQL executed on Red Hat Enterprise Linux Server v6.2 installed on a commodity Dell server fitted with Fusion ioDriveDuo based Flash memory and the same amount of DRAM as 3 nodes of Clustrix (144GB).
The comprehensive report provides the following details (such that the results can be reproduced):
