livejournal outage post mortem

(only tangentally on topic)

Interesting tail on the problems of MyISAM tables, disk write-caching,
and sharing space with people who can't resist pushing the big red

I wonder what livejournal would look like if they used pg instead
mysql. They had to figure out some ways of working around the
pessimistic locking of the non-MVCC approach, but they've also made
use of the replication features that might not have been available
until recently in pg.
