This processor provides a direct mapping of an Avro field to a JSON field, such that the resulting JSON will have the same hierarchical structure as the Avro document. Note that the Avro schema information will be lost, as this is not a translation from binary Avro to JSON formatted Avro. The output JSON is encoded the UTF-8 encoding. If an incoming FlowFile contains a stream of multiple Avro records, the resultant FlowFile will contain a JSON Array containing all of the Avro records or a sequence of JSON Objects. If an incoming FlowFile does not contain any records, an empty JSON object is the output. Empty/Single Avro record FlowFile inputs are optionally wrapped in a container as dictated by 'Wrap Single Record'</p><h3>Tags: </h3><p>avro, convert, json</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong>.
