From MySQL Fulltext Search to Sphinx
+0 Vote Up -0Vote Down
MySQL fulltext search (FTS) is old and well known. It has a simple setup and requires only small changes for querying. For many people it’s more than enough to provide fulltext search. So, here’s the question: why add a new variable – Sphinx – into the system when the database already has the basic functionality? [...]
MariaDB patches for Random Query Generator
+3 Vote Up -0Vote Down

My fellow testers and others who run RQG tests on MySQL flavors might be interested in some additions that are being used for MariaDB testing. While none of them is a major breakthrough, maybe they will make somebody’s life a little easier.

RQG Introduction

A quick introduction for those who have never heard of RQG, but are still curious what this blog post is about.

RQG stands for Random Query Generator, also known as randgen — an open-source product, available under the GPL v2 license. Quoting its home page on Launchpad, it is a “pseudo-random data and query generator that can be used to test any Perl DBI, JDBC or ODBC-compatible SQL server, in particular MySQL, but also JavaDB and PostgreSQL”.

The framework was created by my former

MySQL man pages silently relicensed away from GPL
+7 Vote Up -3Vote Down

It has recently been brought to our attention that the MySQL man pages have been relicensed. The change was made rather silently going from MySQL 5.5.30 to MySQL 5.5.31. This affects all pages in the man/ directory of the source code.

You can tell the changes have come during this short timeframe (5.5.30->5.5.31). The old manual pages were released under the following license:

This documentation is free software; you can redistribute it and/or modify it only under the terms of the GNU General Public License as published by the Free Software Foundation; version 2 of the License.

The new man pages (following 5.5.31 and greater – still valid for 5.5.32) are released under the following license:

This software and related documentation are provided under a license agreement containing restrictions on use

The MySQL Cluster storage engine
+2 Vote Up -0Vote Down

This is one close to my heart. I’ve recently written on other storage engines: Where are they now: MySQL Storage EnginesThe MERGE storage engine: not dead, just resting…. or forgotten and The MEMORY storage engine. Today, it’s the turn of MySQL Cluster.

Like InnoDB, MySQL Cluster started outside of MySQL. Those of you paying attention at home may notice a correlation between storage engines not written exclusively for MySQL and being at all successful.

On performance of JDBC drivers.
+4 Vote Up -1Vote Down

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

Percona Live Conference Notes
+3 Vote Up -0Vote Down

This is the required post about things I observed during this years MySQL conference.

Things that are awesome:

  • The tables in sessions. I think these were here last year. They are still awesome this year.
  • The new style power plugs. They solved the problem of people tripping over daisy chained power strips and the strips being accidentally turned off.
  • Massive quantities of coffee and real cream.

Things that can be improved:

  • Lunch tickets. I overheard the same conversation a dozen times about people not being able to find their lunch tickets or not really knowing about them.
  • Make badges reversible. A badge under observation will be facing the wrong way.

Things that just bumped me:

  • The music is different this year. Now it makes me feel like a teenager struggling with a breakup.

Database Master-Slave Replication in the Cloud
+1 Vote Up -1Vote Down
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
