I was reviewing the Percona Live sponsors list the other day and pondering the potential success stories associated with this product or that one…. and as I was preparing to put more thought on the topic, a PlanetMySQL post caught my eye. It was penned by Mike Hogan and titled, “Thoughts on Xeround and Free!”

For some reason the author of that post makes a connection between a free account in a cloud-based service and Open Source software. I think it’s an incorrect analogy, as they are two totally different things. A “free account” in this case is really just a marketing tool. Well, I admit there are companies that also use the “Open …

Back when the first version of the MariaDB Java Client was released, someone asked in the comments about the performance characteristics of the driver compared to ConnectorJ. I answered with hand-waving, saying that nobody does anything stupid, the performance of the drivers would be roughly the same, but I promised to measure it and tell the world one day. And now that day has come. The day where three MySQL JDBC drivers (ConnectorJ, MariaDB JDBC, and Drizzle JDBC) are compared against each other. Unlike the server, which gets benchmarking attention all the time, there is no standard benchmark for connectors, so I needed to improvise, while trying to keep the overhead of the server minimal. So I did something very primitive to start. I used my two favorite queries:

• DO 1 — this one does not retrieve a result set, and thus can be seen as a small “update”.
• SELECT 1 — the minimal …

dm-cache is (albeit still classified “experimental”) is in the just released Linux 3.9 kernel. It deals with generic block devices and uses the device mapper framework. While there have been a few other similar tools flying around, since this one has been adopted into the kernel it looks like this will be the one that you’ll be seeing the most in to the future. It saves sysadmins the hassle of compiling extra stuff for a system.

A typical use is for an SSD to cache a HDD. Similar to a battery backed RAID controller, the objective is to insulate the application from latency caused by the mechanical device, the most laggy part of which is seek time (measured in milliseconds). Giventhe  relatively high storage capacity of an SSD (in the hundreds of GBs), this allows you to mostly disregard the mechanical latency for writes and that’s very useful for database systems such as MariaDB.

That covers writes (for the moment), but …

I attended the OpenWest Conference in Orem, Utah, and have to say its one of the best community organised conferences. There were over 840+ people at the conference (with more walk-in’s), representing a greater than 100% growth rate compared to last year’s conference.

I gave a talk about MariaDB, and its safe to say that we’ve got many new features that that it’s getting very hard to go in-depth in a span of an hour.

One of the highlights for me was attending talks. I give so many talks, and spend a lot of time talking to people about MariaDB and MySQL, that I very rarely get to see other talks or learn new things. So OpenWest was very welcome from that aspect.

On Thursday, I saw a wonderful …

The MariaDB project is pleased to announce the immediate availability of the MariaDB Java Client 1.1.2. This is a Stable (GA) release.

Last week I had to present a tutorial at Percona Live 2013, a presentation at SkySQL’s MySQL & Cloud Database Solution Day and last but not least, a presentation on a Saturday morning at Linuxfest Northwest. It wasn’t easy, but giving the presentations after our announcement early in the week about going open source was very exciting given the warm reception we got from the MySQL Community.

This is a guest post from Jelastic.

Many developers use master-slave replication to solve a number of different problems, including problems with performance, supporting the backup of different databases, and as a part of a larger solution to alleviate system failures. Traditionally, master-slave replication is done with real servers, but it can also be done with cloud database servers. This guest post from Jelastic (originally published here) describes how to set up MariaDB master-slave replication using their Jelastic PaaS (Platform as a Service).

Replication Overview

Master-slave replication enables data from one database server (the master) to be replicated to one or more other database servers (the …

5 years of MySQL

People often write a blog post when they reach some nice anniversary since they joined MySQL community. Well, for those old enough it usually means when they joined MySQL AB as employee. For me this was January 2008. Because I didn't remember the month correctly, I haven't blogged anything then, but decided to save it for a better opportunity - now.

TL;DR Starting this week I will be working for 10gen, selling MongoDB to the Nordics. This blog post is really long - even then it doesn't contain the most interesting stories, I'm not sure if they can ever be published. Sorry for the length, but remember you don't need to read all at once. This is my last MySQL post so save some of it for cold winter days!

I wasn’t at the MySQL Conference this year but it was very nice to follow this event from Paris.
Of course I didn’t feel the general atmosphere by visiting booths or met fabulous people.
But it was a great opportunity to offer you a live post about the conference with an external point of view.

Twitter, RSS feeds (yes Google, I still use RSS), Planet MySQL and infiltrators were my best friends during this crazy week.

I would like to summarize the major announcements and events occurs during this tenth edition.
