At the end of 2007, the first alpha of MySQL 6.0 was released. Alpha is the key word here, 5.0 was in decent shape by this stage, 5.1 was not ready and there were at least rumors of a MySQL 6.1 tree. I’ll go into MySQL 6.0 later, but since you’re no doubt not running it, you can probably guess the end of that story.

The big news of 2008 was that at the last MySQL AB all company meeting, the first and last one to occur while I was with the company, in January 2008 in Orlando, Florida, it was announced that Sun Microsystems was going to acquire MySQL AB for the sum of ONE BILLION DOLLARS. Unfortunately, there were no Dr Evil costumes at the event. However, much to the amusement of the Sun employees who were present at the announcement, there was Vodka.

So, while the storage engine project that was to be the savior of and the future of the company, Falcon, had the same name as a Swedish beer (that I’ve actually …

You may think that you have to buy, install, and get up to speed on a new database if you want to work with large amounts of data, but you can do more than you think with the MySQL you already have.

SPEAKER: Jon Tobin, Tokutek
DATE: Thursday, March 20th
TIME: 1pm ET

Without having to change your application or do special tuning you can increase performance and save significant time and money when you need to scale.

Join Tokutek’s Jon Tobin as he demonstrates how to use MySQL or MariaDB in Big Data applications by simply upgrading the storage engine with TokuDB, and how to effectively evaluate TokuDB for increased performance, compression and agility.

During this webinar you will learn:

• How to dramatically increase …

Parallel replication is in MariaDB 10.0. I did some benchmarks on the code in 10.0.9. The results are quite good! Here is a graph that shows a 10-times improvement when enabling parallel replication:

The graph shows the transaction per second as a function of number of slave worker threads, when the slave is executing events from the master at full speed. The master binlog was generated with sysbench oltp.lua. When the binlog is enabled on the slave and made crash-safe (--sync-binlog=1 --innodb-flush-log-at-trx-commit=1), the slave is about ten times faster at 12 worker threads and above compared to the old single-threaded replication.

These results are for in-order parallel replication. With in-order, transactions are committed on the …

(This is part 9 in a series, part 8 is here – because reverse chronological order totally makes sense here)

So, back around 2007, somebody noticed that an awful lot of the downloads of MySQL and associated utilities from mysql.com were for Windows. Of course, it’s then immediately pointed out that the vast majority of Linux users will not be heading to mysql.com to download MySQL, instead using the packages from their distribution.

However, the number of people working on MySQL who had ever even attempted to compile the MySQL server on Windows when given the number of mysql users on Windows was… well…. rather embarrassing. This is very common with free and open source software – especially historically.

If you look back 10 years, Linux on the …

PECL/mysqlnd_ms 1.6 is currently being modified to support sharding and fully automatic server and client failover when using MySQL Fabric (slides) to manage a farm of MySQL servers. PECL/mysqlnd_ms is a mostly transparent load balancer that works with all PHP MySQL APIs (PDO_MySQL, mysqli, …). The idea is, that if, for example, a MySQL server fails, the plugin talks to MySQL Fabric to learn about alternative servers that Fabric has provisioned automatically. This “talks to” gives implies a performance penalty for applications. One worth looking at, to understand it. One worth looking …

I am in Las Vegas this week at the Live 360 Conference for Microsoft Developers. There is a lot of interest in using MySQL with the Entity Framework object-relational mapper and I have been pointing to Using an Entity Framework Entity as a Windows Forms Data Source. So for all you who asked, here is the blog post I promised with relevant link.

Monitoring MySQL and effectively managing it can be challenging. Identifying issues before they grow into performance problems that impact end users can be crucial. Knowing which tools to use, which key metrics to monitor, and how to resolve issues can be enormously important. When considering these facts, we at Percona decided to take steps to provide our Support customers with the tools, alerts, and advice they need to have higher performing, more secure, and easier to manage MySQL deployments.

Percona Support Now Includes MONyog and Percona Advisors

I am pleased to announce that Percona now provides our Gold and Platinum Percona Support for MySQL customers with the enterprise grade tools and advice they need for better performance, fewer database issues, and effective monitoring of MySQL. We have partnered with Webyog to provide our customers with MONyog …
