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 friendlist_graph [...]
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, [...]
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 [...]
Many configs have thread_stack_size configured explicitly, but that can cause rather bad trouble:
if the stack inside a thread it’s too small, you can get segfault crashes (stack overflow, essentially). Particularly on 64-bit.
if the stack is too large, your system cannot handle as many connections since it all eats RAM.
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 [...]
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 implemented [...]
This alliance is an excellent step, showing the maturity, breadth and depth of expertise for MySQL related services! Of course Open Query is an active early member, with our training and subscription services, and initiatives like the OurDelta builds project.
Kudos to MontyW and PeterZ for driving this further while at the MySQL Conference last month.
