As per the documentation, publish.changed.documents.only=true property allows users to only publish the actual documents after inserts, replaces or updates.

But after setting this property to true also I am seeing the below fields in the output.

"_id":

{ "_data": "825D5A10BE000000012B022C0100296E5A1004F921F092F2D34BBDAF3B274E9CA70CDF46645F696400645D5A10BEE3CFEA2BABAC124E0004" }

,
"operationType": "insert",
"clusterTime": {
"$timestamp":

{ "t": 1566183614, "i": 1 }

}

 

Am I missing something here? My requirement is I want only the actual document to be sent to the Kafka topic.
