MySQL
The MySQL track at Kaleidoscope in Washington, DC during June 28-July 1st is set! Here is the schedule, Lincoln VI is the MySQL track room. It’s not too late to register for Kaleidoscope – be sure to use the discount code MYSQL to save $300 off your registration (assuming you are not a member of ODTUG).
I have been talking with a group of folks who have been making a product that has lots of free functionality, including the ability to centrally manage many MySQL instances. The administration functions include starting and stopping MySQL, seeing status and system variables, seeing and managing the MySQL config file (/etc/my.cnf), seeing and managing accounts, a small dashboard of overall health graphs, and more.
This article will explain why changing the sort_buffer_size kills performance and stability, it will also talk more about understanding why, an integral part against the “Battle against any guess.” Baron’s recommendation to leave sort_buffer_size as the default is just as bad as all the advice given to change the sort_buffer_size, because all that advice (including Baron’s) does not explain the underlying causes.
I have a hard time trying to figure out the deeper meaning behind Peter’s post, given that Percona writes a storage engine for MySQL, XtraDB. Does this mean that Percona will stop developing XtraDB? Does this mean that the Percona Server will diverge farther and farther away from MySQL so that they’re not compatible any more and migrating from MySQL to Percona Server is very difficult?
We have confirmed that there will be an entire MySQL track at Kaleidoscope! Because Kaleidoscope is less than 8 weeks away, we could not go through a standard call for papers. Ronald and I have been working to come up with appropriate topics and speakers for an audience that uses MySQL but is probably more familiar with Oracle.
Here’s a matrix of all the videos up on YouTube for the 2010 O’Reilly MySQL Conference and Expo. They are grouped mostly by topic, except for the main stage events (keynote, ignite) and interviews. If there’s a detail missing (ie, slides, or there are other videos you know about), please add a comment so I can make this a complete matrix.
This is not my notes about the MySQL conference that just occurred. These are my thoughts about MySQL conferences in general. During this year’s conference, I heard a lot of concern about whether or not O’Reilly would have a MySQL conference, and whether or not Oracle would decide to sponsor. I heard all of the following (in no particular order):
The morning’s keynotes again were quite good especially the one from Ubunto. I attend another packed Facebook session and one from Ronald Bradford. It was the first time I head him speak and he is very good. I didn’t attend many of the afternoon events because of customer commitments but the remain group at the hotel had a passionate discussion on Oracle role in the MySQL community so its far from over and Oracle has one year to fix it. See you all next year
We started with the morning keynotes again today and I was a little surprised at the snipping going on. The first session that I attended today were around MySQL partitioning in the beta releases and beyond. The next set of sessions were on IO bottlenecks, MySQL data warehousing and finally Danil’s Security session. Finally there was the Ignite session that just finished a few minutes ago which was quite entertaining with lots of nice rapid fire topics. That’s all for today…Last day tomorrow
Well the first day has come and gone and I really enjoyed my first day as a newbie. The keynote from Oracle was well received, they touched on the new Beta version of MySQL and the new mysql enterprise which to a trained oracle eye is looking more and more like Grid Control. The end result is providing more instrumentation to help the DBA but I am a little disappointed that a lot of that instrumentation is not actually in the database itself which forces you to buy the product.
