MySQL Belgian Days 2024 and FOSDEM 2024

In this past week, I’ve been able not just to read or watch digital content online but to meet people in person. In Brussels, first at the MySQL Belgian Days 2024 event, followed by FOSDEM 2024.

There was a wide array of presentations covering many different topics; this is just a summary. Fred talked history of Command Line Monitoring and an intro to the new player Dolphie. Dave Stokes talked security, Sunny Bains gave us a brain dump of TiDB scalable architecture. We got an update on PMM and MySQL on k8s from Peter Zaitsev as well as a chat about his new product coroot. And then a great intro to a new generation of online schema change at scale with Sprit by Morgan Tocker. Alex Rubin shows us how not how to hack MySQL, but how MySQL can hack you. We have all crossed paths as MySQL Inc. employees or MySQL community members since 2006.

Marcelo Altmann gave us a detailed intro of a new era of caching with ReadySet. We also heard updates on Vitess. And that was just Day 1 presentations. The evening event was at the incredibly wall-to-wall packed Delirium Café, sponsored by ReadySet, which we offer great thanks and cheers.

Day 2 was packed with great content about MySQL Shell, MySQL Heatwave ML and Vector, MySQL Router, and the MySQL optimizer from many well-known Oracle MySQLers before amazing awards, Belgian beer, and black vodka, of course.

Congratulations Giuseppe Maxia on your MySQL Legends award at MySQL Belgium Days 2024. It is well deserved for all of your community contributions over the decades.

Check out the details at Unveiling the Highlights: A Look Back at MySQL Belgian Days 2024.

Saturday and Sunday were FOSDEM 24 and its usual location. So many people crossing the university, tunnels, and weird transit paths between all the university lecture halls it can feel like a blur. For the first time, I had no fixed agenda so I could check out random talks on random topics.

A shout-out to many people I know and some new people I met. Colin Charles, Alkin Tezuysal, Walter Heck, Charly Batista, Robert Hodges, Jens Bollmann, Monty Widenius, Matthias Crauwels, Michael Pope, Marcelo Altmann, Emerson Gaudencio, Aldo Junior and tons more I have forgotten to mention by name. There were many conversations also with random community people I didn’t even get names, for example, the team at Canonical.

About “Digital Tech Trek Digest”

Most days, I take some time early in the morning to scan my inbox newsletters, the news, LinkedIn, or other sources to read something new about professional and personal topics of interest. I turn what I read into actionable notes in a short, committed time window, summarizing what I learned, what I should learn and use, or what is of random interest. And thus my Digital Tech Trek.

Some of my regular sources include TLDR, Forbes Daily, ThoughWorks Podcasts, Daily Dose of Data Science and BoringCashCow. Also Scientific American Technology, Fareed’s Global Briefing, Software Design: Tidy First? by Kent Beck, Last Week in AWS to name a few.

Upcoming MySQL Conferences

by

Unlike previous years when the number of conferences with MySQL content diminishes after the O’Reilly MySQL and OSCON conferences (Open SQL Camp excluded), this year has a lot on offer.

This month:

Upcoming next month in September:

  • MySQL Sunday at Oracle Open World on September 18 in San Francisco includes 4 tracks and around 15 quality speakers. (Big numbers of attendees also rumored but yet unconfirmed).
  • The inaugural Surge Scalability conference in Baltimore will include presentations by myself and Baron Schwartz (Percona being sponsors) as well as talks from other popular sites using MySQL.

If your in SF for the MySQL Sunday you may also want to come for the SF MySQL Meetup on the preceeding Thursday night where I’ll be giving my talk on “Common MySQL Scalability problems, and how to fix them”.

In October:

  • Open SQL Camp in Boston from Friday, Oct 15th in the evening, ending Sunday Oct 17th

Europeans will be busy in November where you will find dedicated MySQL tracks with multiple speakers at DOAG and UKOUG. Other MySQL talks can be found at SAPO Codebits 2010 and BGOUG.

And for South America, stay tuned. October will be your month!

There is also a great event calendar maintained by the MySQL community team on the Forge.

One advantage of Oracle/Sun/MySQL

by

This weeks’ announcement Oracle to by Sun was a major talking point at the 2009 MySQL Conference & Expo. While it is too early to even speculate what the future holds with the official MySQL product, for myself a speaker on MySQL topics, Oracle Open World is now a target market.

In addition to many years of providing MySQL for the Oracle DBA Resources I have with the recent closure of call for papers submitted two sessions for consideration.

Integrating MySQL into your Oracle DBA management processes

Most large enterprise organizations use more then one RDBMS product to service business requirements. With the increase in MySQL usage for web based applications such as self-service content, Oracle DBA’s need to understand and appreciate the minimum to ensure performance and availability meets client expectations.

Just how to you integrate MySQL into existing and existing Oracle database infrastructure and management monitoring process?
What are the critical monitoring components? How do these compare to current Oracle Best Practices.
Understand the various end user tools support multiple RDBMS products including Oracle and MySQL.

In this session, DBA’s will leave with the essential knowledge and appreciation of MySQL management.

An overview for evaluating migrating from Oracle to MySQL

MySQL is becoming increasing popular RDBMS for web based applications due to it’s ease of use, availability within the the LAMP stack and large number of open source applications. While implementing MySQL for a new development project may be easy, migrating existing databases, data and applications to use MySQL is not. In this presentation, we will answer questions including:

What are the major challenges to overcome to consider MySQL for some portion of your business?
What are the issues in application portability?
What are ideal applications to consider for migration?
Tools, Products and options for easy migration?
What Oracle features are not supported?

A change in the MySQL Binary distributions

by

Yesterday was the surprise announcement of MySQL 5.4 at the 2009 MySQL Conference and Expo. It was unfortunate that the supporting information was not that forthcoming on the MySQL website. I tried for several hours to try and download, but no mirrors were initially available. Today I see some information on the mysql.com home page and finally able to get the binary.

What I found most significant with this new major version release is a change in the binary distribution, as seen on the Download page.

MySQL 5.4 is only available on 3 platforms:

  • Linux (AMD64 / Intel EM64T)
  • Solaris 10 (SPARC, 64-bit)
  • Solaris 10 (AMD64 / Intel EM64T, 64-bit)

I was also surprised that this beta release highlights the emphasis of community contributions (long overdue), yet the community and indeed many employees of Sun/MySQL were simply unaware of this work. This is clearly a change in involving the community. While I applaud the beta status, hopefully a more stable product to start with, it’s development was done in a very closed company model.

Setting up MySQL on Amazon Web Services (AWS) Presentation

by

On Tuesday at the MySQL Camp 2009 in Santa Clara I presented Setting up MySQL on Amazon Web Services (AWS).

This presentation assumed you know nothing about AWS, and have no account. With Internet access via a Browser and a valid Credit Card, you can have your own running Web Server on the Internet in under 10 minutes, just point and click.

We also step into some more detail online click and point and supplied command line tools to demonstrate some more advanced usage.

Classic quotes – Community One East

by

The CommunityOne East 2009 conference has finished up. There were a few classic statements made by the speakers during the day. They included.

“We have a community reception, that’s a long way to say free beer.”

“Google is the dial tone of the Internet, if it’s not there people start freaking out.”

“I am an insom-maniac, a late night hacker.”

“Having a successful catastrophic – Achieving your marketing goals, and your site crashes due to the load.”

“Ruby is a beautiful expressive fun language.”

(talking about cloud providers) — “Lock-in, it’s like marriage, it’s not necessarily a bad thing.”

“It wasn’t a red carpet, but it was carpeted.”

Your Code, Your Community, Your Cloud… Project Kenai

by

Following the opening keynote announcement about Kenai I ventured into a talk on Project Kenai.

With today’s economy, the drive is towards efficiency is certainly a key consideration, it was quoted that dedicated hosting servers only run at 30% efficiency.

An overview again of Cloud Computing

  • Economics – Pay as you go,
  • Developer Centric – rapid self provisioning, api-driven, faster deployment
  • Flexibility – standard services, elastic, on demand, multi-tenant

Types of Clouds

  • Public – pay as you go, multi-tenant application and services
  • Private – Cloud computing model run within a company’s own data center
  • Mixed – Mixed user of public and private clouds according to applications

SmugMug was referenced as a Mixed Cloud example.

Cloud Layers

  • Infrastructure as a Services – Basic storage and computer capabilities offer as a service (eg. AWS)
  • Platform as a Service – Developer platform with build-in services. e.g. Google App Engine
  • Software as Service – applications offered on demand over the network e.g salesforce.com

Some issues raised about this layers included.

  • IaaS issues include Service Level, Privacy, Security, Cost of Exit
  • PaaS interesting point, one that is the bane of MySQL performance tuning, that is instrumentation
  • SaaS nothing you need to download, you take the pieces you need, interact with the cloud. More services simply like doing your Tax online.

Sun offers Project Kenai as well as Zembly.

Project Kenai

  • A platform and ecosystem for developers.
  • Freely host open source projects and code.
  • Connect, community, collaborate and Code with peers
  • Eventually easily deploy application/services to “clouds”

Kenai Features

  • Code Repository with SVN, Mercurial, or an external repository
  • Issue tracking with bugzilla, jira
  • collaboration tools such as wiki, forums, mailing lists
  • document hosting
  • your profile
  • administrative role

Within Kenai you can open up to 5 open source projects and various metrics of the respositories, issue trackers, wiki etc.

The benefits were given as the features are integrated into your project, not distributed across different sites. Agile development within the project sees a release every 2 weeks. Integration with NetBeans and Eclipse is underway.

Kenai is targeted as being the core of the next generation of Sun’s collaboration tools. However when I asked for more details about uptake in Sun, it’s only a request, not a requirement for internal teams.

The API’s for the Sun Cloud are at http://kenai.com/projects/suncloudapis.

Everybody is talking About Clouds

by

From the opening keynote at CommunityOne East we begin with Everybody is talking About Clouds.

It’s difficult to get a good definition, the opening cloud definition today was Software/Platform/Storage/Database/Infrastructure as a service. Grid Computing, Visualization, Utility Computing, Application Hosting. Basically all the buzz words we currently know.

Cloud computing has the ideals of truly bringing a freedom of choice. For inside or outside of an enterprise, the lower the barrier, time and cost into freedom of choice give opportunities including:

  • Self-service provisioning
  • Scale up, Scale down.
  • Pay for only what you use.

Sun’s Vision has existed since 1984 with “The NETWORK is the Computer”.

Today, Sun’s View includes Many Clouds, Public and Private, Tuned up for different application needs, geographical, political, with a goal of being Open and Compatible.

How do we think into the future for developing and deploying into the cloud? The answer given today was, The Sun Open Cloud Platform which includes the set of core technologies, API’s and protocols that Sun hopes to see uptake among many different providers.

The Sun Cloud Platform

  • Products and Technologies – VirtualBox, Sun xVM, Q-Laser, MySQL
  • Expertise and Services
  • Partners – Zmanda, Rightscale, Kickapps
  • Open Communities – Glashfish, Java, Open Office, Zfs, Netbeans, Eucalyptus

The Sun Cloud includes:

  • Compute Service
  • Storage Service
  • Virtual Data Center
  • Open API – Public, RESTful, Java, Python, Ruby

The public API has been released today and is available under Kenai. It includes two key points:

  • Everything is a resource http GET, POST, PUT etc
  • A single starting point, other URI’s are discoverable.

What was initially showed was CLI interface exmaples, great to see this still is common, a demonstration using drag and drop via a web interface was also given, showing a load balanced, multi-teired, multi server environment. This was started and tested during the presentation.

Then Using Cyberduck (a WebDAV client on Mac OS/X) and being able to access the storage component at storage.network.com directly, then from Open Office you now get options to Get/Save to Cloud ( using TwoGuys.com, Virtual Data Center example document).

Seamless integration between the tools, and the service. That was impressive.

More information at sun.com/cloud. You can get more details also at the Sun Microsystems Unveils Open Cloud PlatformOfficial Press Release.

CommunityOne East – An open developer conference

by

With an opening video from thru-you.com – an individual taking random you-tube video and producing video mashup’s, the CommunityOne East conference in New York, NY beings.

The opening introduction was by Chief Sustainability Officer Dave Douglas. Interesting job title.

His initial discussion was around what is the relationship between technology and society. A plug for his upcoming book “Citizen Engineer” – The responsibilities of a 21st Century Engineer. He quotes “Crisis loves an Innovation” by Jonathan Schwartz, and extends with “Crisis loves a Community”.

He asks us to consider the wider community ecosystem such as schools, towns, governments, NGO’s etc with our usage and knowledge of technology.
