We are using Replicate with a MongoDB Source and an Oracle Target.
We would really like the AR_H_COMMIT_TIMESTAMP/AR_H_TIMESTAMP header columns to be populated with a timestamp value that has greater precision than a second.
Other sources populate those columns down to the millisecond, but it only goes down to the second with a MongoDB Source.
The MongoDB Oplog does contain a commit timestamp field that has the greater precision, but the current one that is being pulled from the Oplog only goes down to the second.
