Anti-RDBMS: A list of distributed key-value stores

Perhaps you’re considering using a dedicated key-value or document store instead of a traditional relational database. Reasons for this might include:

1. You’re suffering from Cloud-computing Mania.
2. You need an excuse to ‘get your Erlang on’
3. You heard CouchDB was cool.
4. You hate MySQL, and although PostgreSQL is much better, it still doesn’t have decent replication. There’s no chance you’re buying Oracle licenses.
5. Your data is stored and retrieved mainly by primary key, without complex joins.
6. You have a non-trivial amount of data, and the thought of managing lots of RDBMS shards and replication failure scenarios gives you the fear.
