class AWS::DynamoDB::Binary
Use this class to wrap strings that you want Amazon DynamoDB
to store as a binary attribute. This can reduce the size of larger attributes to save on storage costs.
table = AWS::DynamoDB.new.tables['data-table'] table.hash_key = { 'id' => :string } table.range_key = { 'position' => :number } # put an item with a binary data attribute table.items.create( 'id' => 'abc', 'position' => 5, 'data' => AWS::DynamoDB::Binary.new('abc') )
