  • Name (String)

Thread

Composite primary key:

  • ForumName (String)

  • Subject (String)

Reply

Composite primary key:

  • Id (String)

  • ReplyDateTime (String)

The Reply table has a global secondary index named PostedBy-Message-Index. This index will facilitate queries on two non-key attributes of the Reply table.

For more information about these tables, see Use Case 1: Product Catalog and Use Case 2: Forum Application.

Sample Data Files

The following sections show the sample data files that are used for loading the ProductCatalog, Forum, Thread and Reply tables.

Each data file contains multiple PutRequest elements, each of which contain a single item. These PutRequest elements are used as input to the BatchWriteItem operation, using the AWS Command Line Interface (AWS CLI).

For more information, see Step 2: Load Data into Tables in Creating Tables and Loading Sample Data.
