-----------------------------------
Summary: Retrieve multiple JSON Document Attributes from DynamoDB
Key: NIFI-7570
URL: https://issues.apache.org/jira/browse/NIFI-7570
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Affects Versions: 1.11.4
Reporter: Andy LoPresto
Multiple users have requested the ability to retrieve multiple "JSON Document
Attribute" values from AWS DynamoDB. Currently, the {{GetDynamoDB}} processor
only allows the retrieval of a single document attribute during invocation.
Possible avenues to implement this include a regex for selecting multiple JSON
document attributes or a comma-separated enumerated list. The destination of
the data is also a concern -- currently the response becomes the flowfile
content. If multiple keys are queried, perhaps a nested JSON document would be
returned into the flowfile content. Or a new processor {{GetDynamoDBRecord}}
could be introduced which formats the response into NiFi record elements.
