Oracle Announces Paid MySQL Add-ons

 Oracle starts charging for MySQL Add-ons

Exciting news, Oracle just announced commercial MySQL extensions that they'll be offering paid extensions to the core MySQL free product.

To be sure, this has raised waves of concern among the community, but on the whole I suspect it will be a good thing for MySQL.  This brings more commercial addons to the table, which only increases the options for customers.  Many will continue to use the core database product only, and avoid license hassles while others will surely embark on a hybrid approach if it solves their everyday business problems.

Speaking of licensing, back in May, Amazon announced that it's RDS or Relational Database Service would now offer Oracle as an option. …

Speaking at Percona Live in London October 24-25

I'll be speaking about MySQL in the Cloud at Percona Live in London October 24-25 and this will be talk centered on our experiences of running a database setup, based on MySQL but with serveral complementary technologies, in Mamzon EC2.

I will talk about our experiences so far, we have a lot of data at Recorded Future and we are also write intensive, which is a slight difference from what you may be used to from other Web-based systems. The amount of data we have right now is in the multi Tb range, and we are growing fast. Is a could environment really useful for something like this? What does work and what doesn't?

Also, I will talk a bit on what I think the technological issues are here when using traditional servers such as MySQL and MongoDB, and how I would like it to work instead. Finally, I'll take a shot at looking at some alternatives that I …

Regarding the MySQL Conference and Expo 2012

Last week, Baron Schwartz announced the Percona Live MySQL Conference and Expo 2012.

Percona organized MySQL related conferences and seminars before, and from what I've heard, with considerable success and to satisfaction of its attendees, and there's one coming up in London in October 2011. But arguably, last week's announcement is quite different from the prior Percona conferences. It's different, because it seeks to replace the annual O'Reilly MySQL Conference and Expo.

Everyone that has read the announcement will have no trouble recognizing it as a replacement, …

xtrabackup incremental backups

We wanted to optimize and test backups for one of our new large scale setup before we could finalize on the backup plan. Our challenge was the data volume was almost 30x more than our normal volumes. Since this involved large volume of data we thought this might be a good candidate to test incremental backups. We wrote a wrapper script to save the states between full backups and incremental backups and did some tests with smaller data sets. It worked perfectly fine. The version of xtrabackup we were testing was 1.6.2.

The incremental backups were completing well within 30minutes. We set out to test what would happen if the amount of incremental diff was large. While doing this test, we started getting backup failures with the following error

The MySQL conference is back for 2012, courtesy of Percona

The past few years of MySQL conferences...

Every year since Oracle's acquisition of MySQL in 2009, there's been some uncertainty around the annual MySQL conference, which used to be co-organized by MySQL AB (in charge of content) and O'Reilly (conference logistics). As my career unfolded during those years, I've seen relatively close how the conferences of 2010 and 2011 happened. As there's been a lot of re-structuring in the community around various forks and new employers, I've felt that the annual conference was the one thing that kept us together, the one common forum where everyone would meet. For this reason I have been personally very engaged (as have many others) in helping O'Reilly get through the conferences of 2010 and 2011 and I'm very grateful to Tim, Gina and the rest of the O'Reilly team that they have provided us with this forum and gravitation point for the past two years.

During this years conference it was openly …

Call for disclosure on MySQL Conference 2012

Percona has announced Percona Live MySQL Conference and Expo 2012. Kudos for their vision and entrepreneurship. I have seen comments praising their commitment to the community and their willingness to filling a void. I have to dot a few i's and cross some t's on this matter.
That was not the only game in town.By the end of June, there were strong clues that O'Reilly was not going to organize a conference. The question of who could fill the void started to pop up. The MySQL Council started exploring the options for a community-driven conference to replace the missing one. The general plan was along the lines of "let's see who is in, and eventually run a conference without the big organizer. If nobody steps up, the IOUG can offer a venue in Las Vegas for an independent MySQL conference". The plan required general …

Google and Microsoft trade patent claims. Actuate announces Q2 results. And more.

# Google accused Microsoft, Oracle, Apple and other companies of organising a hostile patent campaign against Android. That prompted Microsoft executives to claim that Microsoft invited Google to be involved in the CPTN purchase of Novell’s patents. However, Google explained that joining CPTN might have decreased its ability to defend itself against potential patent claims.

How to Run a Streaming Backup with innobackupex

On many of our clients, we have a need to run XtraBackup as a regular OS user. Aside from running into the issue where tar4ibd was not provided with Percona’s xtrabackup-1.6.2.tar.gz package, our main issues have been with permissions when attempting a streaming backup.

I have found the following:

  1. The user needs permissions for a temp directory to stream to/from. The my.cnf of the target database cannot be used because the user does not have permission to write to /tmp/mysql-stdout, so we set a tmpdir in a separate defaults-file.
  2. A backup target directory must be used that the user has read/write permissions to. It seems to me a target directory should not be needed for a streaming backup, …
