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 [...]
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 Drupal users. The [...]
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 [...]
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 [...]
At this point we have a 32-bit and a 64-bit Linux binary tarball, should work on most Ubuntu and CentOS and the like (I tested a few). Possibly OSX coming. Not sure on Windows right now. For further details and download links, see yesterday’s release post.
It’s time to play! A special thanks particularly to Antony Curtis for the excellent smart and actually very speedy coding, and for just being a great guy to work with. If you would like to utilise his ace MySQL knowledge and coding skills, do talk to me! Right now, we have a source tarball available [...]
Antony and I are busy getting the Open Query GRAPH Engine code ready so you all can play with it, but we needed to test with a larger dataset to make sure all was fundamentally well with the system. We have some intersting suitable dataset sources, but the first we tried in ernest because it [...]
The GRAPH engine allows you to deal with hierarchies and graphs in a purely relational way. So, we can find all children of an item, path from an item to a root node, shortest path between two items, and so on, each with a simple basic query structure using standard SQL grammar. The engine is [...]
