Adopting Apache Cassandra

Good overview but some contrast/comparison with MongoDB would be useful

My sense is that MongoDB is the most widely used no-sql db today and so some comparison to it would be useful.
On the face of it, Mongo offers some features that are missing in Cassandra today:
- adhoc query capability using a javascript type language
- ability to run server side script functions
- auto sharding (mongo shards and balances the distribution, automatically)
- map-reduce with server side scripts
It seems that Cassandra is better at handling a large volume of writes but requires programming to perform queries and data processing.
Mongo has some notion of 'client tunable' consistency but I am still grapling with that.
For data mining (where you load data less fequently and do many queries) would Mongo be a better choice? If large volume of writes are required then Cassandra should be favored?
