How can I handle oracle decimal numbers with the GoldenGate "Kafka" / "Kafka connect" handler?

Question

I want to use Oracle GoldenGate (the orcale cdc tool) to integrate the oracle with Kafka. I found two handlers:

• http://docs.oracle.com/goldengate/bd123110/gg-bd/GADBD/using-kafka-connect-handler.htm#GADBD-GUID-81730248-AC12-438E-AF82-48C7002178EC with avro formatter
• http://docs.oracle.com/goldengate/bd123110/gg-bd/GADBD/using-kafka-handler.htm#GADBD449

Both of these handlers do not support the decimal type (I mean that they do not treat the decimal value in avro as a logical type, otherwise), these tools simply convert the decimal to double type. And in this case, we lose accuracy.

Does anyone know a good way to handle decimals other than writing your own handler?
