UpdateDatabaseDdlRequest class
Enqueues the given DDL statements to be applied, in order but not necessarily all at once, to the database schema at some point (or points) in the future.
The server checks that the statements are executable (syntactically valid,
name tables that exist, etc.) before enqueueing them, but they may still
fail upon later execution (e.g., if a statement from another batch of
statements is applied first and it conflicts in some way, or if there is
some data-related problem like a NULL value in a column to which NOT NULL would be added). If a statement fails, all subsequent statements in
the batch are automatically cancelled. Each batch of statements is assigned
a name which can be used with the Operations API to monitor progress. See
the operation_id field for more details.
