As you may know, I own the London Open Source Databases meetup. I mentioned this group in some previous articles, see the Community and new category. Here I want to announce the next two events, that will see two database world stars coming to London and talking to our community. And a change in the group policy, to make it more community-driven and make the engagement grow.

4th July: Peter Zaitsev, Percona CEO

Peter Zaitsev is Percona CEO and co-founder. He doesn’t need a long presentation, but you can read something more about him in the event page.

Peter will talk about Ten things developers should know about databases. The talk, I’ve been told, is also suitable for DBAs. It will be followed by an Ask me anything session, which we can use to satisfy our curiosities about Percona, open source databases, Peter’s views… whatever. A great opportunity to interact with him.

Lightning talks from the community will open the event, and the Call for Papers is open. See below for more information.

Just like our first event, this meetup is sponsored by Percona. Thank you again, guys! Like the first time, I want to say a special thanks to someone who’s usually behind the scenes, as a community manager: Lorraine Pocklington.

Peter Zaitsev, Percona’s CEO, will be at our meetup. He will give a talk, and will answer any question from the community. Before his talk, there will be the opportunity for some of us to give lightning talks, with a length of 5 minutes. THE CALL FOR PAPER FOR LIGHTNING TALKS IS OPEN! We’d really love to see some lightning talks to open the evening…

15th July: MariaDB and MySQL dad meets the London Community!

Monty Widenius is the original author of MySQL and MariaDB, and is currently MariaDB Foundation foundar, and MariaDB CTO. There are many rumors and legends about him, like his ability to produce an insane amount of code quickly. Come and check yourself what is true and what is not.

Vicențiu Ciorbaru works at MariaDB Foundation as a software engineer. But if you occasionally go at MySQL and MariaDB events, you are very likely to know him as a speaker. I saw a couple of his talks and enjoyed his attitude to divulge what developers are doing, while answering any question.

Vicentiu’s talk is MariaDB and MySQL – What Statistics Optimizer Needs Or When and How Not to Use Indexes. Don’t be scared if it sounds a bit technical: Vicentiu will make it simple, and this topic is vital if you care about queries performance.

I’ve been told informally that Monty’s talk will be a Birds Of A Feather kind of thing. More precisely: We get drinks, sit in a circle and everybody bombards Monty with nice questions. I don’t know what you think, but for me sitting down drinking and asking question to the creator of my favorite database servers is brilliant.

This meetup will also start with lightning talks, and the Call for Paper is open. Again: see below for more info.

This meetup is sponsored by the MariaDB Foundation. They will pay for the venue, drinks and food. Thank you, Foundation!

Lightning talks

Lightning talks will open both the event. The purpose is to involve more people, and let them actively participate the events.

This will be a great opportunity to give a short, low-effort talk in a friendly and informal environment, at the presence of a database star. The speakers will talk to an audience of passionate database professionals.

The lightning talks have a 5 minutes length. This is very important to make sure that the next speakers have the opportunity to talk. Most people will come to the event after work, and some of them have a lengthy travel to go home. Still, in 5 minutes you can say a lot of things – plus info on how to learn more about the topic, if you want to.

A committee for the meetup

This is the change I mentioned at the beginning of the article. This meetup was until now organised by a single person, me. There is nothing wrong with this, but it is not what I want.

What I’d like to see is a meetup where more people help with decisions about next meetups: topics to cover, speakers to invite, sponsors, etc. And of course they will also need to help with organisation, which is a relief for me. I will not ask them to contribute with money.

If you want to be part of the committee, please send an email to

See you there!

I wish you a happy DBA Appreciation Day! This “celebration” is an idea from my former colleague Federico Campoli, the author of pg_chameleon. Incidentally it occurs on 5th July, the day after the meetup with Peter. If you are a DBA, send the link to your colleagues. If you aren’t, consider offering a beer to your fellow DBAs.

I hope to see you at the next London Open Source Databases meetups, if you are near London and you like the topics.

Stay fresh, cheese bags!
