// UpdateGlobalTableRequest returns a request value for making API operation for
// Amazon DynamoDB.
//
// 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.
