Slides from Failover or not Failover, that is the question
+0 Vote Up -0Vote Down

Below are the slides from my last talk at this Percona Live Worldwide MySQL Conference. The idea for this talk was proposed by my co-presenter Massimo Brignoli and goes back to a debate on this topic that went through the MySQL blogosphere during last Autumn - which in itself was sparked by an outstanding retrospective published about a MySQL failure at Github.

MySQL Community Awards 2013 - And the winners are...
+5 Vote Up -0Vote Down

MySQL Community Awards 2013 were announced earlier today at the MySQL Conference & Expo...

***

It's time again to award persons, applications and companies in the MySQL Community. This is an annual tradition to highlight and give appreciation to some of the things that make MySQL so great.

The first awards were given out in 2005, and since 2010 the winners have been chosen by a community panel of which myself and Shlomi Noach are the co-secretaries. There has been a public nomination period in January and the final voting is done by a panel who are themselves former winners of the award.

The first category is

Good morning Percona Live visitors! Attached to this post you can find a spreadsheet (both LibreOffice or Excel, as you prefer) that you can use towards the end of my tutorial. I've also attached the slides so you can download a copy of them.

The MEMORY storage engine
+3 Vote Up -0Vote Down

I recently wrote about Where are they now: MySQL Storage Engines and The MERGE storage engine: not dead, just resting…. or forgotten. Today, it’s the turn of the MEMORY storage engine – otherwise known as HEAP.

This is yet another piece of the MySQL server that sits largely unmaintained and unloved. The MySQL Manual even claims that it supports encryption… with the caveat of having to use the SQL functions for encryption/decryption rather than in the engine itself (so,

Hiring: Perl programmer, PHP programmer, UI/UX consultant
+0 Vote Up -0Vote Down

I don’t get to say this often, but “I’m hiring” (at Percona):

I’ve been with Percona for about 5 years, so I can tell you: it’s probably the best company to work at: great pay, great benefits, great people, and truly driven by a desire to do right by customers and do good work.  What more can you ask for?  Of course, all these jobs are MySQL-related: Perl + MySQL, PHP + MySQL–maybe the UI/UX job less so, but still close enough.

Detecting if a MySQL server supports partitioning
+0 Vote Up -0Vote Down

This morning, this Percona XtraBackup bug came to my attention: https://bugs.launchpad.net/bugs/1170340 - basically, it’s now really quite tricky to determine if a MySQL server you’re connected to supports partitioning or not.

If you’re connected to anything less than MySQL 5.6, you can use have_partitioning variable. But since that’s gone in 5.6, you’re going to get a false negative if you’re connected to 5.6. You could use INFORMATION_SCHEMA.PLUGINS table, but that’s not there in 5.0, so you have some added workarounds to add there too.

A simple version check could be the solution… but what if you compiled the server without partitioning support?

The state of the MySQL ecosystem

I’ll be on a whistle-stop tour of California next week, including two presentations at the Percona Live MySQL Conference and Expo.

On day one at 1:20pm I’ll be presenting CAP Theorem: Two out of three ain’t right, in which I will be challenging the popular ‘two out of three’ explanation of CAP Theorem, examining the evidence from a variety of experts, including Dr Eric Brewer.

Then on day three at 9:00am I’m very honoured to be providing a keynote presentation, The State of the MySQL Ecosystem.

Here’s an overview of the presentation:
