BigCouch clustering is a lot like Couchbase Server’s clustering. (I don’t know enough details of either one to describe the differences, but at a high level they both work the same way, by partitioning the keyspace and giving each node ownership of a subset of the keys.) XDCR (Cross-Data-Center Replication) is a different protocol used to replicate changes between Couchbase clusters that are not in close contact, for example if you run an application in geographically dispersed data centers. It has a similar role to CouchDB replication, although the actual protocols are completely different, and XDCR is less sophisticated since Couchbase doesn’t track revision histories of documents. —Jens
