What is the best practice when creating tables?

[kyto64]

In my service, when a value does not exist in a table, I store that value.

When traversing the table, if the table does not exist, of course Aws::DynamoDB::Errors::ResourceNotFoundException is raised.
Is it a best practice to create the table in advance, e.g. rake dynamoid:create_tables, to prevent this expected exception from occurring?

Note that I do not want to check for the existence of the table each time the table is traversed in logic, for performance reasons.

Any ideas would be appreciated.
Thanks.

Tables creation is kind of database management area that IMHO is not a responsibility or purpose of an ORM. AFAIK a table creation on the fly is just a handy way to initialise a database or table in the test environment.

So it isn't a common practice AFAIK to create tables using Dynamoid in production environment.
