MySQL NL Community Meetup with MariaDB speakers summary
+2 Vote Up -0Vote Down

Last week we had the MySQL Meetup with MariaDB Developers in Amsterdam, which went on easily for about 3.5 hours. Thanks to all for listening (these were lightning talks, not with a strict 5 minute clock with Q&A thrown in), and Daniël van Eeden for organising this at the eBay offices (whom kindly provided pizza, beer and soft drinks as well). We had many talks, …

Using Persistent Memory in RDBMS
+0 Vote Up -0Vote Down

People at Intel started the pmem library project some time ago, it’s open to the broader community at GitHub and  other developers, including Linux kernel devs, are actively involved.

While the library does allow interaction with an SSD using a good-old-filesystem, we know that addressing SSD through SATA or SAS is very inefficient. That said, the type of storage architecture that SSD uses does require significant management for write levelling and verifying so that the device as a whole actually lasts, and your data is kept safe: in theory you could write to an NVRAM chip, and not know when it didn’t …

1 Million SQL Queries per second: GA MariaDB 10.1 on POWER8
+0 Vote Up -0Vote Down

A couple of days ago, MariaDB announced that MariaDB 10.1 is stable GA – around 19 months since the GA of MariaDB 10.0. With MariaDB 10.1 comes some important scalabiity improvements, especially for POWER8 systems. On POWER, we’re a bit unique in that we’re on the higher end of CPUs, have many cores, and up to 8 threads per core (selectable at …

Binlog Servers for Simplifying Point in Time Recovery
+0 Vote Up -0Vote Down

A common way to implement point in time recovery capability is:

to regularly do a full backup of a database, and to save the binary logs of that database (or from its master if doing backups on a slave).

When point in time recovery is required you need to:

restore a backup, and apply the binary logs up to the point of recovery.

(Step # 2 and # b above are the ones that will be simplified

Do not run those commands with MariaDB GTIDs - part # 2

Update 2016-01-30: restarting the IO_THREAD might be considered useful in some situations (avoiding MDEV-9138).  Look for "in contrast, if the IO thread was also stopped first" in MDEV-6589 for more information.

In a previous post, I listed some sequences of commands that you should not run on a MariaDB slave that is lagging and which is using the GTID protocol.  Those are the following (do not

Do not run those commands with MariaDB GTIDs - part # 1

In the spirit of sharing war stories and avoiding others to do the same mistakes as I did, here are some sequences of commands that you should avoid to run on a MariaDB slave that is lagging and which is using the GTID protocol.  Remember, do not run those because...

So, those bad commands are the following:

"STOP SLAVE; START SLAVE UNTIL ...;", or "STOP SLAVE; START SLAVE;" (to remove an

Advanced MySQL Server Auditing
+0 Vote Up -0Vote Down



We remember when we first started auditing MySQL servers, there were very few tools available.  In one of our early big gigs, we were battling serious performance issues for a client.  At the time, tuning-primer.sh was about the only tool available that could be used to diagnose performance bottlenecks.  Fortunately, with a lot of manual interpolation of the raw data it presented, we were able to find the issue with the server and suggest how to resolve them.  For that we are very thankful.  It was a first step in analyzing MySQL status variables, minimizing the number of formulas to learn and calculate by hand.  Obviously …

MySQL-Sandbox 3.1.01 - First release after the change
+0 Vote Up -0Vote Down

I have released MySQL-Sandbox 3.1.01, which is the first release after the move to GitHub. While the changes are not so spectacular (it's a minor release, with mostly bug fixes), I am pleased to see that the move has started producing collaboration. Two of the changes were provided by Daniël van Eeden and Mark Leith, who have scratched some of their own itches by providing useful patches.

All in all, this period of working with GitHub …

Percona Live Europe is now over, MySQL is not
+0 Vote Up -0Vote Down

Percona Live Europe is now more than a week away. l left Amsterdam with a positive thought: it has been the best European event for MySQL so far. Maybe the reason is that I saw the attendance increasing, or maybe it was the quality of the talks, or because I heard others making the same comment, and I also saw a reinvigorated MySQL ecosystem.
There are three main aspects I want to highlight.

1. MySQL 5.7 and the strong presence of the Oracle/MySQL team
There have been good talks and keynotes on MySQL 5.7. It is a sign of the strong commitment of Oracle towards MySQL. I think there is an even more important point. The most …
