Introducing Digg’s IDDB Infrastructure. IDDB is Digg’s new infrastructure component for sharding data across multiple databases, with support for both MySQL and memcachedb. “The DiggBar and URL minifying service is powered by a 16 machine IDDB cluster, which includes 8 write masters in the index and 8 MySQL storage nodes.” # 3rd April 2009, 8:42 pm

New Gearman Server & Library in C, MySQL UDFs. Gearman, the job queue written for LiveJournal and now used by Digg and Yahoo!, has been rewritten in C. Looks like a good candidate for an easily configured lightweight message queue. Also includes hooks for writing MySQL functions that can interact with queues. # 13th January 2009, 4:41 pm
