I have no idea why they don't use something dynamo based like Riak or Cassandra which actually can automatically shard data and scale really well... CouchDB

I have no idea why they don't use something dynamo based like Riak or Cassandra which actually can automatically shard data and scale really well... CouchDB only supports replication, no sharding unless you use third party libraries. With Riak they could use the internal map/reduce support and with Cassandra they might be able to use Hadoop to analyze data and split the workload over several nodes.

If you read the case study you will see that building apps rapidly was a huge win for them. CouchDB gets compared with other DB's but it is a full stack app dev environment. The other NoSQL DB's need a Rails or PHP or Python or Java or C# or ... stack in front and app dev is nowhere as fast as with CouchApp.

  Riak e.g. does also have a REST interface (https://wiki.basho.com/display/RIAK/REST+API https://wiki.basho.com/display/RIAK/REST+API). Could you elaborate what else ist part of the "full stack app dev"? Futon? p.s. please don't use "Rails" when you mean "Ruby". Kittens are dying everytime!

They use it to store aggregated reports for distribution and analysis. It isn't doing any heavy lifting, and it's not a terribly compelling case study of anything.

  Wouldn't it be a good case study in rapid development of a web based aggregate reporting portal? :-)
