For enormous datasets that cannot be efficiently hosted on one cluster, RavenDB v6.0 includes sharding. Like different volumes of an encyclopedia, a sharded database is spread across multiple nodes. These nodes can be distributed across different machines and in different locations.
RavenDB founder Oren Eini (Ayende @ Rahien) explains the various sharding features available in our next release. He discusses how they work and how to effectively spread a gigantic global dataset into distinct shards in ways that maximize efficiency.
