Call for Papers: "MySQL and Friends" Developer Room at FOSDEM 2011 (Feb. 5th, Brussels, BE)

It's that time of the year again — the nice folks at FOSDEM have granted us a developer room at their upcoming conference (February 5+6 2011 in Brussels, Belgium)!

Fosdem 2010

Fosdem 2010 was my 10th fosdem Edition (including the first OSDEM)
As every year Fosdem suffered even more from it's own success.

On Friday evening ther was the obligatory Beer event... however as people need to eat to .. the Devops crowd fled the scene

I had made reservations for a 20 something group and with the CentOS crowd joining us (as there was some overlap anyhow) we were 25 when we arrived in the restaurant .

Dinner and Discussions were great .. I learned about some new projects and we had some insightfull dicussions on how fat your thin foil should be ...

After dinner we went back to the Beer Event were lots of Free Beer was tasted ...

Saturday was the first full day of Fosdem, as usual Fosdem was the victim of it's own success , too much interresting stuff to see .. too little time.

Lots of Devrooms had the "FULL" sign put up more than you want as a visitor ...
I …

Multi-Master Manager for MySQL – FOSDEM 2010

The next presentation by Piotr Biel from Percona was on Multi-Master Manager for MySQL.

The introduction included a discussion of the popular MySQL HA solutions including:

  • MySQL Master-slave replication with failover
  • MMM managed bi-directional replication
  • Heartbeat/SAN
  • Heartbeat/DRBD
  • NDB Cluster

A key problem that was clarified in the talk is the discussion of Multi-Master and this IS NOT master-master. You only write to a single node. With MySQL is this critical because MySQL replication does not manage collision detection.

The MMM Cluster Elements are:

  • monitoring node
  • database nodes

And the Application Components are:

  • mon
  • agent
  • angel

MMM works with 3 layers.

  • Network Layer – uses a virtual IP address, related to servers, not …

MySQL Developers Room at FOSDEM 2010



I am in Brussels, waiting to attend FOSDEM 2010, one of the biggest open source gatherings in Europe, taking place this weekend in Brussels.
On Sunday, there is a Developers Room for MySQL and Friends, with 14 talks from open source professionals coming from Europe and North America.


The novelty of this round of talks is that thy will be 20 minutes long, rather than 1 hour. This will force all presenters to be more cautious about their timing, and to concentrate their talks on the essential. Even the experienced ones, who have given the same talk several times, will have to make an effort to come to the …
