What Hacker News says?
Cassandra is hugely biased towards making writes fast [1] and there's no indication in either Digg article that they (somehow) changed that fact in their deployment by tuning. Digg loads the complexity during the write by denormalizing but that load is on the application server not the data store. [1] http://spyced.blogspot.com/2010/01/cassandra-05.html

HN discussion> How do you make pre-commit vetting of code quality scale Use distributed version control, and work on your next patch while waiting on review of your first. Even if you can't use it officially, you can use it locally: http://spyced.blogspot.com/2009/06/patch-oriented-developmen...

HN discussionI disagree. See http://spyced.blogspot.com/2006/07/single-column-primary-keys-should-be.html Particularly the three-part series. Multiple-columns can be hard to deal with. But duplicate rows because you're using an autoincrement integer as your pk are also a pain in the ass. Measure twice, cut once.

HN discussionFirst off - whatever you're doing, you'll probably be fine using either. That said, I'm generally more frustrated when using MySQL than when using PG. Here's a sample of the problems I've encountered from using both MySQL and PG.
