MySQL Conference 2007: First Impressions and Findings
25 Apr2007

So, first two days of mysqlconf’07 are finished now. What can I say is that without any doubts: It worth it! If you’re working on some high traffic projects, some high-loaded database driven systems, etc, you definitely should attend such conferences – you’d never be able to get such big amounts of information from the best people in the industry as you can get here.

I’ve been attending mostly practical MySQL scale-out sessions and BOFs and I’ve got really controversial impressions. No – everybody was great, controversial thing is my own level – I never before was so sure that I know nothing at all! I see people here for which most of new things for me (especially in MySQL scaling) are pretty obvious and it is hard to keep myself from some kind of self-beating because I don’t know these things.

Interesting thing happened today – I clearly realized why YouTube guys got their billion and we or someone else didn’t – IMHO – one of the major factors was their ability to handle all these users traffic efficiently. They’ve got one of the best (imho) technical people in their command. I was really impressed by one of their guys (sorry, but I’m too bad in remembering people’s names) – one of the two founders – who participated in MySQL replication and scale out BOF as attendee. He clearly showed me that they’re able to grow almost without any limits because of their skills which is one of the major requirements in today’s fast changung world.

Another interesting thing was that I realized that my spoken English could be really good when people speak clearly and I understand their questions. I spoke with some guys about our mmm project, about maby things and there was no problems at all!

So, its going pretty late and tomorrow going to be a long day so I want to repeat – if you have any chance to get on such conferences, DO IT! If your company can’t help you, spend your own money or find some other solutions, but DO IT! It is the best thing could happen to YOU as professional!

P.S. Just remembered – I saw some women-DBAs today! Really smart girls! I never thought that pretty girl can become such great IT prefessional and now I know – I was really wrong.

P.P.S. Sorry to russian-speaking readers – I will definitely translate my last posts later – just when I’ll come back home from this crazy (but the best) event with 14hrs of load a day


Master-Master Replication Example using MMM
23 Apr2007

Despite of my high load at work I decided to release mmm-1.0-pre2 today. There are some small, but critical fixes added and much more coming next week (or little bit later if mysqlconf will take more time than I think).

After the first alpha release I’ve received lots of emails, some messages in mmm-devel mail list and even some bug reports in Google Code bug tracking. One of the most asked things was documentation. ;-) So, I decided to write some posts in this blog (sorry to non-sql-related readers) and them compose some docs for final release using these posts and comments from readers. This post will be first in mmm-series and will describe how to use mmm in simple master+master scheme where one master accept write requests and both masters accept read requests. This post will provide you with detailed instructions about MySQL setup, permissions setting, mmm installation and configuration and cluster management.

Как клонировать виртуальную машину при использовании VmWare Server
8 Apr2007

Сегодня занимался предрелизным тестированием нашего ПО и очень нужна был конструкция из трех отдельных серверов с запущенными MySQL’ями. После коротких раздумий я пришел к выводу, что проще всего будет использовать мою “старую” рабочую машину (на самом деле, это неплохой Sempron с 2Gb RAM, но сейчас я использую мой macbook в качечтве рабочей станции) и поставить на нее 3 отдельных виртуальных сервера. Конечно, как все админы, я ленивый и потому ставить Debian 3 раза подряд мне не показалось правильным решением ;-). Потому было принято решение создать одну машину, поставить на нее свежий Debian Etch и потом поискать варианты клонирования этой машины чтобы исаользовать ее в 3-х копиях. Когда все было закончено, я решил потратить сэкономленное время на то, чтобы написать эту небольшую заметку и рассказать, как простыми средствами создать клом машины в VmWare Server.

Релиз ПО для управления кластерами с MySQL Master-Master репликацией
5 Apr2007

Очень много времени прошло с момента моего последнего поста здесь. Много работы и практически полное отсутствие новых технологий в работе – вот основные причины. Ео сегодня я с удовольствием хочу аннонсировать здесь очень интересный проект: MySQL Master-Master replication manager – набор очень гибких скриптов для управления различными схемами установки MySQL, в которых используется master-master репликация.

Более детальная информация о проекте может быть найдена в детальном обзоре в блоге Петра Зайцева (на самом деле, программа создавалась мной для одного из его клиентов) или на странице проекта. Все вопросы и замечания можно отправлять в группу MMM development на Google Groups. Если вы хотите поддержать данный анонс на Digg.com, я буду не против. ;-)
