Moral of the upcoming story: when your systems rely on someone else’s software, make sure you test it thoroughly to understand how it works. I found a couple of interesting things about the go-mysql-driver driver for Go. One is that it prepares every query before executing it, and then closes it afterwards, if you’re just using the db.Query() or db.QueryRow() functionality. There is zero benefit to this; Bill Karwin has probably listed it as an antipattern somewhere.

The  MariaDB Foundation announcement spawned some interesting commentary about the state of open source databases.  One recent headline cited the "beleaguered MySQL community." Beleaguered is a delightful adjective.  The OED tells us that it means beset, invested, or besieged.  Much as I like the word, I do not think it is an accurate or useful description of the MySQL community.  This article and others like it miss the point of what is happening to MySQL and its users.

Let's start by disproving that the notion that the MySQL community is beleaguered.  I don't …

Well, it’s that time of the year again for top ten lists. There have been many versions showing up on the web the last few days, including Time Magazine’s “Top 10 Everything of 2012″ list, with 55 wide ranging lists!

Last year we started using Google Analytics to see what content for blogs was most popular on Tokutek.com and generated a 2011 top ten list, ending up with a few surprises.  This year saw spikes in some interesting areas as well, including flash performance, NASA and Big Data, and MongoDB.

Without further adieu, here is the top ten list for 2012:

Those who’ve been around the MySQL world are probably aware of the much-discussed topics of GPL licensing, dual licensing, and in particular, licensing of the client libraries (also called connectors or drivers) and the FOSS exception to that licensing. This is newly relevant with the announcement of a permissively-licensed MySQL-compatible client library for MariaDB.

The difference is that this time there’s been some question about the provenance and history of the source code. Some people asked me about this. Some of them were aware of a relatively obscure detail: there’ve been permissively licensed MySQL client libraries for years, in the form of libdrizzle, a BSD-licensed library for the Drizzle fork of MySQL.

Here are some of the thoughts that seemed to be going through peoples’ minds:

ClouSE version 1.0b.1.6 is released

OblakSoft is pleased to announce the release of ClouSE version 1.0b.1.6.  In this release we fixed some of the known ClouSE Beta limitations as well as performance and functional bugs reported by our users.

Here is the summary of changes that are included into 1.0b.1.6:

• Support for latest MySQL 5.5

Now ClouSE supports MySQL thru 5.5.29.  To keep the distribution small, we don’t build binaries for MySQL prior to 5.5.19 anymore.  If you need one, please contact us.

• DECIMAL keys support

Now ClouSE supports using DECIMAL fields in keys.  Previously neither the primary key nor indices could include DECIMAL fields.  This fixes the following Beta limitation: DECIMAL fields cannot …

Last week we made a maintenance release for MySQL Connector v1.0 available. The announcement can be read in the MySQL forums and the history log is available online.

Connector/Python v1.0.8 does not introduce anything new, it only comes with bug fixes. Some are quite important and it’s probably good to upgrade.

Please use the MySQL Bugs website to report any problem.
