How MySQL-Sandbox is tested, and tests MySQL in the process
+1 Vote Up -0Vote Down

MySQL-Sandbox is a great tool for testing a new release, and in fact this is what I do when a new MySQL tarball becomes available. I don't think many people are aware of the full testing capabilities of the sandbox, though.

When you think about testing, you may just think of creating a sandbox with the new tarball, and then hammering it with your pet procedure. That works, of course, as the main purpose of MySQL-Sandbox is to allow you to do just that. There is, however, a full test suite that can tell you in a short while if your tarball is compatible with the past or not.

Unexpected Memory Consumption for Bulk Index Creation in InnoDB (MySQL)
+1 Vote Up -0Vote Down

In my last Booking.com Hackathon, I worked on MyISAM vs InnoDB for data loading (LOAD DATA IN FILE) and bulk index creation.  My motivation was the following: knowing that some are still using MyISAM for this particular use-case, I wanted to verify/understand if/why InnoDB is slower than MyISAM.  I do not yet have complete results on this specific subject but I found some interesting things that

MyOraDump, Oracle dump utility, version 1.2
+0 Vote Up -0Vote Down

I have now released version 1.2 of MyOraDump, my Oracle data extraction tool. This version has one new feature, which is transaction support for MySQL format exports which does speed up loading data a lot! Trust me, it really does! Also I have fixed a bug that did cause a crash at the end of the run, I have no idea why this didn't show up before, but there you go and now it is fixed.

MyOraDump 1.2 can be downloaded sourceforge, and as usual there is also a pdf only download if you want to read up on the tool before using it.

MySQL replication in action - Part 1: GTID & Co
+1 Vote Up -0Vote Down

In the theoretical part of this series, we have seen the basics of monitoring. In that article, though, we have barely mentioned the new tools available in MySQL 5.7 and MariaDB 10. Let’s start from something that has the potential of dramatically changing replication as we know it.

Crash-safe tables and Global transaction identifiers in MySQL 5.6 and 5.7

Global transaction identifiers (GTID) is a feature that has been in my wish list for long time, since the times I was working with the MySQL team. By the time I left …

LinuxCon North America in Seattle
+0 Vote Up -0Vote Down

I’m excited to be at LinuxCon North America in Seattle next week (August 17-19 2015). I’ve spoken at many LinuxCon events, and this one won’t be any different. Part of the appeal of the conference is being able to visit a new place every year.

MariaDB Corporation will have a booth, so you’ll always be able to see friendly Rod Allen camped there. In between talks and meetings, there will also be Max Mether and quite possibly all …
