 - `PartitionKey` and `SortKey` now reference the column names in the DynamoDB table and are nested under the `Attributes` field.
-- By default, the value retrieved from `Object.SourceKey` is used as the `PartitionKey` value. If the `SortKey` is provided and the value from `Object.SourceKey` is an array, then the first element is used as the `PartitionKey` value and the second element is used as the `SortKey` value.
