Creating an Amazon DynamoDB Table - AWS SDK for Ruby

Creating an Amazon DynamoDB Table

The following example creates the table Movies with two required attributes: year and title in the us-west-2 region.

The wait_until call blocks you from using the table until DynamoDB has created it. By default, the DynamoDB client’s wait_until method checks every 20 seconds, up to a maximum of 500 seconds, to see if the table was created.
