One of the tasks within Percona Remote DBA is to ensure we have reliable backups with minimal impact. To accomplish this, one of the tools our team uses is called mydumper. We use mydumper for logical backups because of several nice features. Some of them are:

• multithreaded, producing very fast backups compared to mysqldump
• almost no locking, if not using non innodb tables
• built-in compression
• separate files for each table, making it easy to restore single tables or schema, and the possibility to hardlink files reducing the space needed to keep history of backups. Also this feature give you the possibility to restore with more than one thread.

The mydumper project was started at the beginning of 2009 by …

There may be times when you need to create a new table in MySQL and feed it with data from another database, the Internet or from combined data sources. MS Excel is commonly used as the bridge between those data sources and a target MySQL database because of the simplicity it offers to organize the information to then just dump it into a new MySQL table. Although the last bit sounds trivial, it may actually be a cumbersome step, creating ODBC connections within Excel through Microsoft Query may not help since these are normally created to extract data from MySQL into Excel, not the opposite. What if you could do this in a few clicks from within Excel after making your data ready for export to a MySQL database?

With MySQL for Excel you can do this and this guide will teach you how easy it is.

Digging through piles of old stuff in the house, I came across a nice little artifact of MySQL history, an old business card. One benefit of a small company is that you can tend to get your first name @company.com, which of course, I had.

I wonder which other MySQL AB employees still have a business card laying around somewhere?

Firebird is an open-source DBMS with a long history and good SQL support. Although I measured Firebird's importance as smaller than MySQL's or MariaDB's, it exists, and might grow a bit when Firebird becomes the default LibreOffice DBMS.

I decided to compare the current versions of MySQL 5.6 and Firebird SQL 2.5. I only looked at features that end users can see, without benchmarking. Preparing for the comparison was easy. I looked at the instructions for downloading Firebird with Ubuntu and within 15 …

The MySQL Fabric framework brings two major features: automatic client- and server-side failover and sharding. The manual hints, you need a “Fabric aware driver” for this but it does not list one for PHP. First, you don’t necessarily need new drivers! Second, the "driver" for PHP is the current development version of the PECL/mysqlnd_ms replication and load balancing plugin. The plugin covers the sharding but not the failover/HA quickstart example of Fabric: how the plugin works and why you should not use the plugin – yet.

I love it when software gives you elegant ways of solving your problem. Programming language designers make me feel like they care when they take the time to include succinct, powerful expressions. I’ve recently discovered some in new things in MySQL, as well as a few rediscoveries. This is the first five, and I’ll cover the next five in another article.

In

You’ve probably used the standard In operator before:

Select 'Oh yeah!' From dual Where 1 In (1,2,3);

As a side note, the dual table is just a dummy table that always returns one row. It’s useful for demonstrating language features or running experiments.

You can also use a subquery with In:

Select 1 From dual Where 1 In (Select 1);

The thing I discovered was that it’s not just scalar values: it’s actually comparing rows, so you can see if a row is present:

Select 1 From dual Where (1,2) In (Select 1,2); …

Now I’m back in the MySQL fold, I’ve got the opportunity to speak at Percona Live again. I’ve always enjoyed speaking at this conference (back when it was known by another name…), although I need to up my game and do the 6 talks I did back in 2009.

On the Tuesday afternoon, tutorials day, I’m running a half-day session with my replication colleague Linas Virbalas. This will be similar to the session I did at Percona Live London, and cover some of the more advanced content on replication, including, but not limited to:

• Filters
• JavaScript Filtering
• Some fun and practical filters
• Heterogeneous replication from MySQL out to MongoDB, Vertica, Oracle and Hadoop

I might even choose to demo …
