Hey Jaqcues
the link you posted is from an SAP internal WIKI - doesn't really make much sense to put it here in public.
Up to now (SPS10) there's no official direct integration between SAP HANA and Cassandra available.
You might access Cassandra via ODBC (SAP and DataStax enable the Internet Enterprise) and SAP Data Services. But that's about what is available right now.
Not sure why neither of you guys found that page ...
