I've a MongoDB Kafka Connector v1.3 configured with output.json.formatter=com.mongodb.kafka.connect.source.json.formatter.SimplifiedJson, so my UUID field is outputed like that: "_id":"MSRJCs07SFy4sMpopdRvEA==".
But, one of clients of that Kafka message need to convert that SimplifiedJson in a valid ExtendedJson, and from that ExtendedJson instantiate a org.bson.BsonDocument (mongodb Java SDK), so the _id should be recongnized as a BsonBinary (UUID) with value 3124490a-cd3b-485c-b8b0-ca68a5d46f10.
Trying BsonDocument.parse directly from SimplifiedJson, that value "_id":"MSRJCs07SFy4sMpopdRvEA==" is treated as a BsonString.
The client can't do that manually because there is not standard in that field, may be a object id, a uuid or any other thing which make sense to the application that generate that data.
So, there is any built-in way in MongoDB library to convert a SimplifiedJson to a Bson with the same original field types (object id, binary, dates, numbers, etc)?
