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. > https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-mongodb-bundle/nifi-mongodb-processors/src/main/java/org/apache/nifi/processors/mongodb/GetMongo.java#L213 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
