What is the best NoSQL product to scale out?
• There are many flavours of NoSQL:
• Key/Value • Documents • Column-oriented • Objects
www.percona.com
When consider scale out?
• Workset bigger than RAM • High CPU usage • Disk O/I exhausted • Redundancy • Decrease Latency

Let's talk about MongoDB
• A few things that you need to know before scale MongoDB:
• MongoDB has a single master for each replicaset.
• Sharding must be very well configured, otherwise you will only have a few machines idle.
• Look at what you want to scale: • reads? • writes?

Let's talk about MongoDB
• High consistence will cost more time to confirm a operation.
• Downsize is not so easy operation all data will be removed by one single thread, by design.
• Keep your eyes open to MongoS and Config Servers those guys are responsible to keep a shard working.
