There is a feature in Couchbase 4.x that can really help with Global Secondary Index creation and many do not know about.

The user Interface is written in JavaScript while the business logic and data model is written in native Swift/Java. 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. Couchbase Server 5.5 is introducing another way to spread the index load around: index partitioning. Instead of replicating an index, you can now split up the index amongst the nodes with hashing. And, you can use partitioning and replicas together in concert. Index partition replicas will be used automatically, Couchbase Training and Tutorials for Enterprise NoSQL. This free tutorial training, comprised of numerous video tutorials, demonstrations, and hands on lab exercises, teaches how to index, select, filter, aggregate, and calculate JSON data fields, and how to insert, update upsert, join, and delete JSON documents, within a Couchbase data bucket.
