MySQL at Oracle Open World 2016

MySQL is a growing presence at Oracle Open World. While most of the headlines belong to the main products, where Oracle services are aiming at world domination, MySQL shared the spotlight, as it was announced to be part of Oracle database cloud. It seems a logical move for Oracle: after all the effort to make MySQL 5.7 the biggest release ever, it stands to reason that it is offered as a competitive feature in its own database as a service.

With this offer, Oracle is applying enterprise pricing and methodologies to a target of emerging companies. MySQL in the Oracle cloud differs from the competition by a few key points:

  • It's only MySQL 5.7. While this is the most advanced MySQL server …

Lightning talks at Percona Live Amsterdam: come on stage!

The schedule to Percona Live Europe 2016 is being finalized. It should be published soon, and it will include 3 hour and 6 hour tutorials, regular 50-minute talks, and shorter 25-minutes talks. It will not include, however, the lightning talks, a session comprising several 5-minute talks, and they are missing from the initial schedule for two reasons:

  • We want to offer a chance to all attendees to propose a lightning talk for some time. We would like to have more quality material to choose from.
  • They will not be in the conference venue. Instead, they will be hosted at Booking, during the community dinner.

Unlike in previous editions, though, the lightning talks will …

Speaking at FOSDEM: Pseudo GTID and easy replication management

This coming Sunday I'll be presenting Pseudo GTID and easy replication management at FOSDEM, Brussels.

There's been a lot of development on Pseudo GTID these last few weeks. In this talk I'll show you how you can use Pseudo GTID instead of "normal" GTID to easily repoint your slaves, recover from intermediate master failure, promote slaves to masters as well as emply crash safe replication without crash safe replication.

Moreover, I will show how you can achieve all the above with less constraints than GTID, and for bulk operations -- with less overhead and in shorter time. You will also see that Pseudo GTID is a non intrusive solution which does not require you to change anything in your topologies. …

Including Code Samples With rst2pdf

Every document I create these days is written in rst (ReStructuredText) and transformed into something useful using rst2pdf. This includes worksheets, reports, handouts and slide decks. Along the way I've learned a few tricks, and I try to write them down so I can look up how to do something. If this helps you too, then great :)

Start Simple

Include a code block in rst by adding something like this:


.. code-block:: php

Your code must then be indented, and the style persists until you "undent" again. There is pretty extensive language/syntax support since it is built on pygments, so you can use most language names instead of the php there.

Line Numbers and PHP Tags

In order to make the PHP syntax highlight …

Speaking at Percona Live: common_schema, MySQL DevOps

In less than a month I'll be giving these two talks at Percona Live:

If you are still unfamiliar with common_schema, this will make for a good introduction. I'll give you multiple reasons why you would want to use it, and how it would come to immediate use at your company. I do mean immediate, as in previous common_schema presentations I happened to get feedback emails from attendees within the same or next day letting me know how common_schema solved an insistent problem of theirs or how it exposed an unknown status.

I'll review some useful views …

Percona Live - call for "Hall of Shame" talks

We've got some spare time on Percona Live during the lightning talks session, and are spontaneously calling for "Hall of Shame" submissions.

What is this about?

We just had a wonderful Reversim Summit a couple weeks back, where we held the "Hall of Shame" session. We are used to hear talks about success stories and great new technologies. Well, this session is your chance to come up and say: "I messed up, and I'm proud of it!"

You will have 3-4 minutes to tell us about how you once accidentally dropped your database; corrupted your data; brought your company's service down. The greater the damage, the greater the appeal! But we're looking for the funny edge - not for a tragedy. There are no slides. Just a "Hall of Shame" screen behind you.

The response we got on Reversim Summit? It was amazing. The audience was literally in tears; …

Percona Live 2014 schedule released; BoF and Lightning Talks Call for Papers continues

The complete tutorial & session schedule for Percona Live MySQL Conference & Expo 2014 is released. This schedule offers both a sense of achievement as well as a sense of regret; for I believe the schedule is very good, and yet some good proposals had to be left out.

This is an inevitable result of a conference that is popular and receives far more proposals than can fit within the time frames. This conference offers 96 session slots and 16 3-hour tutorial slots. We got well over 300 proposals -- I'm not even sure how to count them -- and they just can't all fit in. My sincere apologies to all those left out. A proposal of mine was just rejected yesterday from another conference; I can sympathize and empathize with all turned down.

As part of our interest in having a diversity of talks and …

common_schema: speaking at Percona Live London, Nov. 2013

In one week's time I'll be presenting common_schema: DBA's framework for MySQL at Percona Live, London.

This talk introduces the rich toolset known as common_schema. It is free, open source, extremely useful in solving DBA & developer tasks, and is the next best thing ever invented next to SQL pie charts.

I'll introduce:

  • Views, with which you can detect and terminate idle transactions, blocking transactions; roll your range partitions; find duplicate keys; block/unblock accounts; get fine grained privileges per account; find AUTO_ICNREMENT free space; ...
  • Routines: do meta executions such as eval(); get query checksums; duplicating accounts; killing suspicious connections; security auditing; parsing JSON data; ... …
