Anders Karlsson wrote about Some myths on Open Source, the way I see it (http://karlssonondatabases.blogspot.com/2014/01/some-myths-on-open-source-way-i-see-it.html) a few days ago. Anders' article is mostly focused on exploding the idea that open source magically creates high quality code. It is sad to say you do not have to look very far to see how true this is. While I largely agree with Ande...

In the last 10 years I have worked a lot with replication systems, and I have developed a keen interest in the topic of multiple masters in a single cluster. My interest has a two distinct origins:On one hand, I have interacted countless times with users who want to use a replication system as a drop-in replacement for a single server. In many cases, especially when users are dealing with applicat...

Let’s say that you want to measure something in your database, and for that you need several operations to happen in parallel. If you have a capable programming language at your disposal (Perl, Python, Ruby, PHP, or Java would fit the bill) you can code a test that sends several transactions in parallel. But if all you have is the shell and the mysql client, things can be trickier. Today...

Old and new MySQL verbosity

I was pleased to see Morgan’s announcement (http://www.tocker.ca/2013/12/09/the-mysql-error-log.html) about a fix to an old problem of mine. In March 2012 I complained about MySQL verbosity (http://datacharmer.blogspot.com/2012/03/mysql-56-too-verbose-when-creating-data.html) during installation. In MySQL 5.7.3, this behavior was changed. While the default is still as loud as it can, you...
