CreateGlobalCluster (action)

        The AWS CLI name for this API is: create-global-cluster.

Creates a Neptune global database spread across multiple Amazon Regions. The global database contains a single primary cluster with read-write capability, and read-only secondary clusters that receive data from the primary cluster through high-speed replication performed by the Neptune storage subsystem.

You can create a global database that is initially empty, and then add a primary cluster and secondary clusters to it, or you can specify an existing Neptune cluster during the create operation to become the primary cluster of the global database.

In other words, the role of the current primary DB cluster and the selected target secondary DB cluster are switched. The selected secondary DB cluster assumes full read/write capabilities for the Neptune global database.

Note

This action applies only to Neptune global databases. This action is only intended for use on healthy Neptune global databases with healthy Neptune DB clusters and no region-wide outages, to test disaster recovery scenarios or to reconfigure the global database topology.
