This nodes retrieves items from DynamoDB that match a given hash and optional range key in a KNIME table.

The command sent to DynamoDB by this node is BatchGet, with a single batch retrieving at most 100 items.

If DynamoDB throttles the requests due to insufficient provisioned capacity units, unprocessed items are included in the next request. Additionally this node employs exponential backoff if throttling occurs. Each time a request cannot be completed fully, the next request is sent after a waiting time of 2^nRetry * 100 milliseconds. Once a request can be executed completely, the retry counter is reset. However, if no item can be retrieved, the node fails and you have to increase the provisioned read capacity units on the table.
