On PostgreSQL. Interview with Bruce Momjian.

“There are four things that motivate open source development teams:
1. The challenge/puzzle of programming, 2. Need for the software, 3. Personal advancement, 4. Belief in open source”
— Bruce Momjian.

On PostgreSQL and the challenges of motivating and managing open source teams, I have interviewed Bruce Momjian, Senior Database Architect at EnterpriseDB, and Co-founder of the PostgreSQL Global Development Group and Core Contributor.

RVZ

Q1. How did you manage to transform PostgreSQL from an abandoned academic project into a commercially viable, now enterprise relational database?

Bruce Momjian: Ever since I was a developer of database …

Introducing Orchestrator: manage and visualize your MySQL replication topologies and get home for dinner

I'm happy to announce the availability of Outbrain's Orchestrator: MySQL replication management & visualization tool.

  • Orchestrator reads your replication topologies (give it one server - be it master or slave - in each topology, and it will reveal the rest).
  • It keeps a state of this topology.
  • It can continuously poll your servers to get an up to date topology map.
  • It visualizes the topology in a clear and slick D3 tree.
  • It allows you to modify your topology; move slaves around. You can use the command line variation, the JSON API, or you can use the web interface.

"Anemomaster": DML visibility. Your must-do for tomorrow

Here's our take of master DML query monitoring at Outbrain (presented April 2014). It took a half-day to code, implement, automate and deploy, and within the first hour of work we managed to catch multiple ill-doing services and scripts. You might want to try this out for yourself.

What's this about?

What queries do you monitor on your MySQL servers? Many don't monitor queries at all, and only look up slow queries on occasion, using pt-query-digest. Some monitor slow queries, where Anemometer (relying on pt-query-digest) is a very good tool. To the extreme, some monitor TCP traffic on all MySQL servers …

Open Source Appreciation Day at Percona Live

I wrote previously about Percona Live Santa Clara 2014, and I want to bring to your attention something Percona has done that is very nice to open source communities: have an open source appreciation day.

Its before the conference (so on Monday), and you get a choice between the CentOS Dojo (great lineup there including many from Red Hat, Monty from MariaDB, and PeterZ from Percona) or the OpenStack Today (another great lineup …

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 …

Open Source Enigma Project

The wild and crazy guys over at S&T Geotronics, James Sanderson and Marc Tessier, have decided to go full tilt with a Kickstarter version of their DIY Open Enigma Project.  For those who missed the fanfare last year, they were featured on Instructables showing how to build an Arduino-based encryption machine that works exactly like a WWII era Enigma.  You know, the thing that Alan friggin' Turing and his team at …

On the road again - FOSSAsia

On the road again - FOSSAsia

It has been a few busy months until now. I have moved from Italy to Thailand, and the move has been my first priority, keeping me from attending FOSDEM and interacting with social media. Now I start catching my breath, and looking around for new events to attend. But before I get into this, let’s make a few things clear:

  • I am still working for Continuent. Actually, it’s because of my company flexibility that I could move to a different country (a different continent, 6 time zones away) without much trouble. Thanks, Continuent! (BTW: Continuent is hiring! )
  • I am still involved with MySQL activities, events, and community matters. I just happen to be in a different time zone, where direct talk with people in Europe and …

Fun with MySQL and Hadoop at SCaLE 12X

It's my pleasure to be presenting at SCaLE 12X on the subject of real-time data loading from MySQL to Hadoop.  This is the first public talk on work at Continuent that enables Tungsten Replicator to move transactions from MySQL to HDFS (Hadoop Distributed File System).  I will explain how replication to Hadoop works, how to set it up, and offer a few words on constructing views of MySQL data using tools like Hive.

As usual with replication everything we are doing on Hadoop replication is open source.  Builds and documentation will be publicly available …

Steven Sinofsky on Disruption

There is a good article over at Re-Code by ex-Microsoft VP Steven Sinofsky called "The Four Stages of Disruption".  It describes the evolution of products and markets through disruption, drawing from Sinofsky's own insights and also building on the work of Everett Rogers ("The Diffusion of Innovations") and Clayton Christensen ("The …

Why I Love Open Source

Anders Karlsson wrote about Some myths on Open Source, the way I see it a few days ago.  Anders' article is mostly focused on exploding the idea that open source magically creates high quality code.  It is sad to say you do not have to look very far to see how true this is.

While I largely agree with Anders' points, there is far more that could be said on this subject, especially on the benefits of open source. I love working on open source software. Here are three reasons that are especially important to me.

1.) Open source is a great way to disseminate technology to users.  In the best cases, it is this easy to get open source products up and running:

$ sudo apt-get install software-i-want-to-use

A lot of software companies ( …
