To set up your global cluster, complete the following steps:
Note: The global cluster must have a primary cluster in one region and secondary clusters in different regions. You can select any region supported by Amazon DocumentDB, with a few exceptions, for creating your secondary cluster. If you are running this lab as part of a formal workshop using Event Engine the default primary region is US East (Ohio).
Note: If using AWS Event Engine only US East (N. Virginia) is allowed as secondary region
Note: If you disabled encryption for the primary cluster, the secondary clusters will not be encrypted.
The regional cluster is now upgraded to a global cluster and the data is automatically replicated from the primary cluster to the secondary cluster(s).
