Currently the keys supported are string and number and value can be json document. In case of hash and range keys both key are required for the operation. The FlowFile content must be JSON. FlowFile content is mapped to the specified Json Document attribute in the DynamoDB item.

Relationships:

NameDescription
unprocessedFlowFiles are routed to unprocessed relationship when DynamoDB is not able to process all the items in the request. Typical reasons are insufficient table throughput capacity and exceeding the maximum bytes per request. Unprocessed FlowFiles can be retried with a new request.
successFlowFiles are routed to success relationship
failureFlowFiles are routed to failure relationship
