MySQL-related events & the ecosystem

I had an interesting conversation with Sheeri (who I’ve known for many years, so consider this friendly banter) on Twitter about my recent blog post titled: once again, a split in events.

Disclaimer/Bias Warning: For those that don’t know me, I write this as a perspective of a community member. I was the first ever Community Engineer at MySQL, followed by being a Community Relations Manager right up till I left Sun Microsystems. I now work on MariaDB which is a branch of MySQL, so naturally we are in competition for user base. But I’m writing this as a community member at large who cares about MySQL & the ecosystem.

First of, this is a focus on the user ecosystem. I think the …

Too many or too big open MyISAM tables??

MySQL tries to be smart and to cram as much performance out of available hardware, and one thing that most MySQLers knows is that opening a table (ie. opening the frm file, and depending on the storage engine, any additional files related to the table) is expensive from a performance point of view. When we see the opened_tables status variable increasing, we tend to increase the table_open_cache setting and keep as many tables as possible open and avoid reopening them.

When it comes to MyISAM though, this has a nasty side-effect. When the server crashes and there are MyISAM tables open, these might well need to be REPAIRed. And if you have big MyISAM tables, this is an issue. Let's say that your application use several MyISAM tables, with the same content, and that you create new tables after a certain time, to keep the size of each individual table down? There are other reasons why you have this effect also, say a large …

Upcoming speaking engagements: Oracle OpenWorld, DOAG Conference

It's that time of the year again — the summer holidays are over and the conference season starts!

I'm very excited to be at Oracle Open World in San Francisco again, where I will pretty busy. On Saturday and Sunday I will attend MySQL Connect, primarily to man the Oracle Linux booth in the exhibition area. But I hope to catch some of the talks as well (I shared my favourite sessions with Keith Larson from the MySQL team in this interview). During Open World, I will help out manning the Oracle Linux demo pods in the exhibition grounds in Moscone South, where we will showcase Oracle Linux with Ksplice and related technologies. I also have a joint presentation with two of our …

Join us at the OTN Sys Admin Day for Oracle Linux and Solaris on Sep. 22nd, Seattle (WA)

Last week we concluded our first Oracle Technology Network Sys Admin Day in Sacramento (CA). Well, it was actually the second Sys Admin Day, but the first one that had two parallel tracks of sessions about both Oracle Linux and Oracle Solaris.

I helped preparing for the event by creating the Linux lab handbook as well as the VirtualBox appliance of Oracle Linux 6.1 that was used for the exercises. Unfortunately I could not be there in person, but it would have been pointless for me to go on an intercontinental flight just for one day.

From the feedback we've received so far, the attendees really enjoyed the event and were positively surprised about the depth and quality of the practical hands-on lab sessions.

If you've missed the first one and happen to live …

What's coming up?

I have a joint session with Chris Mason titled Overview: New Features in Oracle Linux 6 where we'll cover the latest developments. I have another joint presentation with my colleague Rob Young from the MySQL product …

Oracle at fisl12 (Porto Alegre, Brazil, 2011-06-29/2011-07-02)

fisl12 is likely the largest free and open source software event in Latin America. This year, it takes place in Porto Alegre, Brazil, from June 29th to July 2nd. Oracle is a gold sponsor of the event and I will attend it as a speaker. I feel honoured and excited to be there – for me it will be the first visit to the South American continent.

They already have over 3000 registered attendees, so this definitely is going to be a great conference. There is quite a number of well-known names on the speaker roster and I look forward to meeting a lot of familar faces there.

The agenda is still under development but quite impressive already – …
