Subject Re: cassandra as permanent datastore

For click tracking data I might look at Hadoop as well. It can handle  
the writes, replication, etc. along with being mechanisms for  
crunching large datasets built in (e.g. MapReduce).

That being said, you're working with data that, for the most part, it  
won't be the end of the world if you lose a click here or there.  
Cassandra, of course, will handle the HA writes and replication for you.
