For each request you make, Couchbase Server will transparently check the cache for the document you need. Some parts of Couchbase Server, such as N1QL, are written in Go. In some cases, of course, other people are doing great jobs of writing about same. For example, to find a user profile based on that user’s email address, we use the following N1QL query: N1QL allows you to query JSON with the same flexibility you’d expect from a relational database, including JOINs across documents. still uses the Memcached protocol and not the RESTful API of CouchDB. Updates are then replicated to slaves and an HTTP load-balancer, such as nginx, to distribute reads evenly amongst those slaves. Both CouchDB and CouchBase use the same replication system except peer to peer replication. CouchDB was designed with bi-directional replication (or synchronization) and off-line operation in mind. The CouchDB Replication Protocol is not magical, but an agreement on usage of the public CouchDB HTTP REST API to enable Documents to be replicated from Source to Target..
