// Adds or removes replicas in the specified global table. The global table must
// already exist to be able to use this operation. Any replica to be added must be
// empty, have the same name as the global table, have the same key schema, have
// DynamoDB Streams enabled, and have the same provisioned and maximum write
// capacity units. Although you can use UpdateGlobalTable to add replicas and
// remove replicas in a single request, for simplicity we recommend that you issue
// separate requests for adding or removing replicas. If global secondary indexes
// are specified, then the following conditions must also be met:
//
// * The global
// secondary indexes must have the same name.
//
// * The global secondary indexes must
// have the same hash key and sort key (if present).
//
// * The global secondary
// indexes must have the same provisioned and maximum write capacity units.
