SSDs can't be used for everything, take advantage of Couchbase's ability to segregate data storage from index 22 Jul 2013 Now when you press replicate Couchbase will start replicating your existing data into the targeting index within Elasticsearch. Now let's move on Also be sure to consult the store-specific sections for store-specific object mapping, like indexes, customizing To provide the same level of high availability as the Data Service, GSIs also support automatic replication between nodes. These index replicas can then also be used to provide automatic load balancing for incoming N1QL queries. Couchbase provides high availability using intra-cluster replication and index replication, and disaster recovery using cross datacenter replication (XDCR). Intra-cluster replication In the event of failure of a single node, this ensures that data is still available on other nodes that can provide full read and write ability to the applications.

In Couchbase, latency and throughput are significantly impacted by data replication. There are different kinds of data replication models, mainly master-slave (Couchbase, MongoDB, Espresso), master-master (BDR for PostgreSQL, GoldenGate for Oracle) and masterless (Dynamo, Cassandra).
