If your data fits into memory you probably do not need NoSQL.

You may also notice the company that produced the benchmark is a cloudera
partner so they "forgot" to show how much faster couchdb is then hbase in
this scenario, but were more then happy to show you how much "faster" it is
then mongo and cassandra .
