In the documentation for the current release of Oracle GoldenGate for Big Data (220.127.116.11.1.011) there's a helpful sample configuration, which isn't so helpful ...
[...] gg.handler.kafkahandler.ProducerRecordClass = com.company.kafka.CustomProducerRecord [...]
This value for
gg.handler.kafkahandler.ProducerRecordClass will cause a failure when you start the replicat:
[...] Class not found: "com.company.kafka.CustomProducerRecord" [...]
If you comment this configuration item out, it'll use the default (
oracle.goldengate.handler.kafka.DefaultProducerRecord) and work swimingly!
