Oracle will be at Percona Live. This is a great news. Oracle was totally absent at last year edition. Not taking part to business event organized by competitors is a frequent Oracle Corporation behavior. Percona Live is a business event own by Percona (one of Oracle competitor) and some other Oracle competitors like SkySQL/MariaDB will [...]

So, I’ve looked at what sloccount says on the differences between Oracle MySQL over versions of itself and the various MySQL branches around. What I haven’t looked at is the diffstat. Firstly, let’s look at MariaDB.

I’m going to look at MariaDB 5.5.29 as compared to MySQL 5.5.29, both checked out from bzr. A naive diffstat would give us:

5261 files changed, 1086165 insertions(+), 122751 deletions(-)

And this looks like an awful lot of code that has changed: about 1,086,165 lines! This actually includes a whole other copy of InnoDB in the form of XtraDB. If we take that into account we get:

5032 files changed, 864997 insertions(+), 125099 deletions(-)

Which is still incredibly high. Let’s look at what’s changed though. We actually see a bunch of changes in the test suite, some of which are relatively harmless, while others, like the change to rpl_tests/rpl_innodb.test have a …

I have had a lot of folks wanting to know when talks would be during Open Database Camp, and we had enough space in the schedule that we did not need to vote on talks, so I present the Open Database Camp Boston Schedule, now online. Lots of MySQL talks, but also a Mongo talk thrown in for good measure! (still hoping to sneak a Postgres talk in…)

As with any conference schedule, this might change. See you at Harvard University in Cambridge on Saturday and Sunday!

The latest update (v 3.0.9) includes a feature for excluding queries from statistics. To make Jet Profiler ignore certain queries, you need to edit the original query in the application code.

Start the query with /*jp-ignore*/ (no spaces), for example "/*jp-ignore*/ SELECT ... FROM ..."

This will prevent the query from showing up in Top Queries and the other tabs. The query will, however, still affect general preset statistics (such as number of threads running and threads busy). Also make sure that your mysql client library preserves comments - some libraries including the mysql command line client removes comments by default.

As part of Percona Remote DBA for MySQL service we recognize that reliable backups are one of the most important things we can bring to the table. In my experience handling emergencies, the single worst thing that can happen is finding out you don’t have backups available when some sort of data loss or catastrophic event occurs.

With our Remote DBA service we can take care of backups for you, what follows are some of the internals of our implementation.

What kind of outages can happen?

• Someone runs UPDATE or DELETE and forgets the where clause or filters weren’t quite right
• The application had a bug causing data to be removed or overwritten
• A table (or entire schema) was dropped …

Cloud Storage Engine (ClouSE) installation and configuration is now fully automated. Try new ClouSE installer and you’ll have cloud storage access configured in no time.

OblakSoft is pleased to announce the release of Cloud Storage Engine (ClouSE) installer that can be used to deploy and configure ClouSE with your MySQL server. Now ClouSE can be deployed with just one command. The installer will guide the user through the configuration process, prompt for Cloud Storage connection parameters, and install ClouSE into MySQL.

Presented is a step-by-step guide for ClouSE installation and configuration, from downloading the binaries to running the installer. The guide was designed by request of WordPress-to-Cloud users, however it is fully applicable to any generic ClouSE installation.

The slides have notes, they are a little hard to discover with the SlideShare interface, look for a tab below the slide that looks …

One of the most rewarding things you can do is help someone get a great job or hire a great person for the position they need to fill. I have traveled a lot, written books, done a bunch of consulting, and spoken widely on MySQL, other databases, open source, and so forth. I’ve gotten to know a lot of people, some I’d call good friends, and many of them are leading large organizations. I think this is both a privilege and a serious responsibility.

It’s a privilege because I can ask some of these people for help or introductions or advice sometimes. It’s a responsibility because I need to be ready to do something for them, too. In many cases it’s a pay-it-forward kind of readiness.

Many, many people contact me looking for people to hire. I keep a list. When someone tells me they are on the job market, I try to match them with openings I’m aware of, if any are appropriate. (Many fewer people tell me they’re looking for …

Here’s the recording!

I’m off to speak at the Utah Oracle User’s Group Training Days 2013 tomorrow and Thursday. I’m presenting on Oracle Database Triggers and on techniques leveraging PHP and MySQL Striped Views. If you’re not there, you can check this older (but recently updated) post on PHP and MySQL Striped Views.

Hope to see a few folks who use the blog. BTW, I won’t be at Collaborate 2013 this year. Travel budgets are always tight, and this year they’re more than tight.

From my previous posts, we have some numbers (excluding NDB) for the size of MySQL, so what about PostgreSQL? Here, I used PostgreSQL git trunk and classing things in the contrib/ directory as plugins. I put the number of lines of code in the src/backend/storage directory down as storage engines LoC but did not count it as non-kernel code.
