Zambonilli created NIFI-5284:
--------------------------------
Summary: RunMongoAggregation uses ObjectIdSerializer &
SimpleDateFormat
Key: NIFI-5284
URL: https://issues.apache.org/jira/browse/NIFI-5284
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Affects Versions: 1.6.0
Reporter: Zambonilli
The RunMongoAggregation processor uses Jackson to serialize the document to
JSON. However, the default serialization for Jackson on Mongo ObjectId and
dates leaves a lot to be desired. The ObjectId's are serialized into the
decimal representation of each component of the ObjectId instead of the hex
string of the full byte array. Mongo dates are being serialized as unix time as
opposed to ISO8601 zulu string.
It looks like the GetMongo processor has set the correct serializer flags on
Jackson to fix this. The fix for GetMongo is here.
