Speaking in December 2016

I neglected to mention my November appearances but I’ll just write trip reports for all this. December appearances are:

  • A bit of a Japan tour, we will be in Osaka on the 17th, Sapporo on the 19th, and Tokyo on the 21st. A bit of talk of the various proxies as well as the various servers that exist in the MySQL ecosystem.

Looking forward to discussing …

MySQL Support Engineer's Chronicles, Issue #4

This week I had to deal with some unusual problems. But let me start with Percona's xtrabackup, software that I consider a key component of many current production MySQL setups and use regularly. Recently new minor versions of XtraBackup were released, check the details on 2.4.5, for example. It made a step towards support of MariaDB 10.2, but it's still a long way to go, see this pull request #200.

My main problem with xtrabackup, though, is not with lack of support of MariaDB 10,2-specific features. Why should they care, after all... The problem is that old well known bugs and problems are not resolved, those that may affect all MySQL versions, forks and environments. Check  …

Debian and MariaDB Server

GNU/Linux distributions matter, and Debian is one of the most popular ones out there in terms of user base. Its an interesting time as MariaDB Server becomes more divergent compared to upstream MySQL, and people go about choosing default providers of the database.

The MariaDB Server original goals were to be a drop-in replacement. In fact this is how its described (“It is an enhanced, drop-in replacement for MySQL”). We all know that its becoming increasingly hard for that line to be used these days.

Anyhow in March 2016, Debian’s release team has made the decision that going forward, MariaDB Server is what people using …

Upstart Basics for Automatic Restarts of MaxScale After Crash

Historically I do not care much about MariaDB's MaxScale, at least since I know how to build it from source when needed. But, as a support engineer who work at MariaDB, sometimes I have to deal with problems related to MaxScale, and this week it happened so that I had to explain what to do to implement automatic restarts of MaxScale "daemon" in case of crashes on RHEL 6.x.

In the process I had found out that two of my most often used Linux distributions, CentOS 6.x and Ubuntu 14.04, actually use Upstart, so good old System V's init tricks and scripts work there only partially and only because somebody cared to integrate them into this "new" …

MySQL Support Engineer's Chronicles, Issue #3

The original idea of this series was to publish one post per week, but it seems every other week I have some special topic that well deserves a dedicated post. Last week I had no time to complete my writing because of long (and, I hope, useful) Howto post on replacing corrupted partition using non-corrupted one from other server in replication setup. But I had links and notes collected in a draft that I am going to complete now.

First of all, during the previous week I had time to submit two more talks for the  …

Percona Poll: What Database Technologies Are You Using?

Take Percona’s poll on what database technologies you use in your environment.

Different databases get designed for different scenarios. Using one database technology for every situation doesn’t make sense, and can lead to non-optimal solutions for common issues. Big data and IoT applications, high availability, secure backups, security, cloud vs. on-premises deployment: each have a set of requirements that might need a special technology. Relational, document-based, key-value, graphical, column family – there are many options for many problems. More and more, database environments combine more than one solution to address the various needs of an enterprise or application (known as polyglot persistence).

Please take a few seconds and answer the following poll on database technologies. Which are you using? Help …

MySQL Support Engineer's Chronicles, Issue #1

I have a habit to keep a log of everything I work on (or even just read about while working) every day. It's just a plain text file, with date labels, where most lines are URLs of issues and bugs I contributed to somehow, and my comments on what I did and why. But there are also code fragments, texts, copy-pasted outputs and links to interesting sites, articles and documentation.

Some of lines from this log I post on Facebook separately as I add them, these are mostly related to MySQL bugs and other things that annoy me. I know that some of my Facebook friends actually do not like this kind of posts at all... When I used LiveJornal actively, I've posted digests of my log from time to time (you can check what was there if you read Russian). But that digests …

Getting data out of SQL Server in a MariaDB friendly way.

I know what you are thinking "Oh my, it's that time again, Karlsson insist that data should get out of some other database and into MariaDB. What is he up to this time?" and that is exactly right, this time data is coming out of SQL Server, out of that expensive, closed source, Windows-only software and into the lightweight, fast and cost effective MariaDB.

I have already shown how this works when getting data out of Oracle in releasing MyOraDump, so inline with that the corresponding program to get data out of SQL Server is called MyMSSQLDump and it has features along same same lines as MyOraDump. To connect to SQL Server (or Sybase, but this I haven't tested) I use FreeTDS, which is a nice Open Source SQL Server / Sybase driver. The output formats supported are MySQL (i.e. A file with (INSERT …
