Open Query @ DrupalConSF
+0 Vote Up -2Vote Down

Peter and Arjen will be at DrupalCon SF 2010. Peter specifically for the event, Arjen staying around the SF area after the MySQL Conference last week.

Specifically, we’ll be talking with people about using the OQGRAPH engine to help with social graphs and other similar problems, easily inside Drupal. You may recall that Peter already created the friendlist_graph extension for the friendlist Drupal module.

From the MySQL Conf and other earlier feedback, OQGRAPH is proving to be a real enabler. And since it’s free/GPLv2 and integrated in MariaDB 5.2, there’s generally no hindrance in starting to use it.

Walter and I are giving a tutorial on Monday morning, MySQL (and MariaDB) Dual Master Setups with MMM, I believe there are still some seats available – tutorials are a bit extra when you register for the conference, so you do need to sign up if you want to be there! It’s a hands-on tutorial/workshop, we’ll be setting up multiple clusters with dual master and the whole rest of the MMM fun, using VMs on your laptops and a separate wired network. Nothing beats messing with something live, …

Friendlist Graph Module for Drupal
+2 Vote Up -1Vote Down

At DrupalSouth 2010 (Wellington) after LCA2010, Peter and I implemented a Drupal module as a practical example of how the OQGRAPH engine can be used to enable social networking trickery in any website. The friendlist_graph module (available from GitHub) extends friendlist, which implements basic functionality of friends (2-way) and fans (1-way) for …

OQGRAPH at OpenSQL Camp 2009, Portland
+0 Vote Up -0Vote Down

Antony is travelling up to Portland for this great event that’s about to start Fri evening and going over the weekend. He’ll be showing other devs and people more about the OQGRAPH engine, and gathering useful feedback.

Open Query is, together with many others (I see Giuseppe, Facebook, Gear6, Google, Infobright, Jeremy Cole, PrimeBase Technologies, Percona, Monty Program, and lots more), sponsoring the event so that it’s accessible for everybody – reducing the key factor to getting there rather than having to worry about …

OQGRAPH update: speed, maze example, 5.0 packages
+1 Vote Up -0Vote Down

Antony has done a bit of magic, considerably speeding up inserts. Since the base implementation does not have persistence, insert speed is particularly important. Copying the 2×89,051 edges for the Tree-of-Life example is now near-instant.

The delete bug has been fixed.

There’s a new Maze example in the OQGRAPH trunk on Launchpad, first introduced in my MySQL University …

It was fun doing the MySQL University session on OQGRAPH yesterday. Now also available: slides (PDF) and audio/video recording (FLV download, if anyone can convert to a more open format, that’d be great).

OQGRAPH engine on MySQL University – 5 Nov 2009 10:00 UTC
+0 Vote Up -0Vote Down

Only a few weeks after Walter’s session on Multi-Master Replication with MMM and thanks to the great gang at MySQL Docs (my colleagues from long ago!) I’ll be doing a MySQL University session in a few days, about the GRAPH computation engine. From talks/demos I’ve done about it so far, I’ve learnt that people love it but there are lots of interesting questions. After all, it’s a pretty new and in a way exotic thing.

MySQL University uses DimDim, an online presentation service. You’ll see slides, and hear my voice. You can also type questions in a live chat room. We actually …

OQGRAPH on Launchpad, graph examples
+3 Vote Up -0Vote Down

The MySQL 5.0 and MySQL/MariaDB 5.1 source code is now also available through Launchpad. If you were waiting for a version for 5.1 and are ok with building the plugin from source, now you can!

The repo contains a subdir for examples, we’re hoping many people will contribute little snippets and scripts to import and use interesting datasets. To give you a hint, with graph capabilities you are able to deal with RDF data sources. You just need to transform the XML to say CSV, import into a suitable structure, and copy the edge information across to an OQGRAPH table.

Roland Bouman’s …
