-- Creates a global table from an existing table. A global table creates a replication relationship between two or more DynamoDB tables with the same table name in the provided regions.
--
--
-- Tables can only be added as the replicas of a global table group under the following conditions:
--
--     * The tables must have the same name.
--
--     * The tables must contain no items.
--
--     * The tables must have the same hash key and sort key (if present).
--
--     * The tables must have DynamoDB Streams enabled (NEW_AND_OLD_IMAGES).
--
--     * The tables must have same provisioned and maximum write capacity units.
--
--
--
-- 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.
