--
-- 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.
