Managing an Amazon Neptune global database
With the exception of the managed planned failover process, you perform most management operations on the individual clusters that make up a Neptune global database. The managed planned failover process is available only to Neptune global databases, not to individual Neptune DB clusters. To learn more, see Performing managed planned failovers for Neptune global databases.
To recover a Neptune global database from an unplanned outage in its primary region, see Detach-and-promote a Neptune global database in the case of an unplanned outage.
Although you can configure the DB cluster parameter groups independently for each Neptune cluster in a global database, it is best to keep settings consistent among all the clusters to avoid unexpected behavior changes if a secondary cluster is promoted to be the primary. For example, use the same settings for object indexes, streams, and so forth in all the DB clusters.
