Fetching All Items with DynamoDBMapper

Question

I want to get all of the records from a Dynamo DB table and have them mapped into an array of POJOs; The POJO is simple and already annotated.

DynamoDBMapper appears to be the object that will do a fetch to acquire the records and deserialize them into my POJOs. Perhaps using PaginatedScanList() to walk through the entire table.

Mapper's Scan() and PaginatedScanList() methods both require a DynamoDBScanExpression parameter. What DynamoDBScanExpression would be used to select all of the records in the table?

Answer 1

You can pass a new DynamoDBScanExpression() into the scan method.:

mapper.scan(MyObject.class, new DynamoDBScanExpression());

Or you could use the new Document API
