We are looking for a suitable storage engine for our weblog history data. We looked at Bigtable's paper and understand it is suitable to us well.

However, I also understand that Document-oriented-DB such as MongoDB seems to provide a little more powerful schema power -- i.e, it can model our data as well.

I wonder how nowadays ppl choose a scalable NoSQL DB --- I read enough articles like "we looked at A, B and C, and we decided to use C". But I'd like to see some benchmark number. What I am saying is that if MongoDB and the like can provide same level of performance as Bigtable clones, why don't web companies choose it (preparing to deal with various potentially more complex data problem)?

Thanks,

By the way, I read an article (which convinced me at the moment) saying Cassandra does not fit the M/R operation, any comments?
