I personnally did it the other way around : from Cassandra to PostGreSQL, I
needed an hybrid system : Cassandra solidly holds all data while PostGreSQL
holds fewer data but request are simple and efficient ( with SELECT WHERE).
This is pretty easy once you master key browsing and iterating.

I'm currently moving my existing mysql database to cassandra. One particular
problem I have is to migrate all those integer auto-increment ids to
