Something different. A story about lessons learned....

Riak on Drugs (MySQL Dev Project Lessons Learned)

Talks about experience implementing a 5M user healthcare system for Denmark using Riak. Running MySQL and Riak in parallel. Problem with TCP packet corruption not being detected by checksum (replaced network driver). Delta changes using gzip capability to use a dictionary and referencing previous version as dictionary -- clever idea. Erlang used in solution. Good deal of discussion about the system architecture for handling write conflicts.
