nvm on the persistence, it seems like it does support it:

'Since version 1.1 the safer alternative is an append-only file (a
journal) that is written as operations modifying the dataset in memory
are processed. Redis is able to rewrite the append-only file in the
background in order to avoid an indefinite growth of the journal.'

This thread probably shouldn't digress too much from Cassandra's
suitability for session management though..
