I am trying to get Debezium to send my CDC events to Kinesis and the service seems to start but there are errors, and it doesn't seem to be sending anything to Kinesis. I was following this setup guide on the Debezium site:
https://debezium.io/documentation/reference/1.2/operations/debezium-server.html
Here is my config file:
debezium.sink.type=kinesis
debezium.sink.kinesis.region=us-east-1
debezium.source.connector.class=io.debezium.connector.mysql.MySqlConnector
debezium.source.offset.storage.file.filename=data/offsets.dat
debezium.source.offset.flush.interval.ms=0
debezium.source.database.hostname=127.0.0.1
debezium.source.database.id=12345
debezium.source.database.port=3306
debezium.source.database.user=*****
debezium.source.database.password=******
debezium.source.database.dbname=inventory
debezium.source.database.server.name=127.0.0.1
debezium.source.schema.whitelist=inventory
When I run the server using ./run.sh, the server seems to begin starting then I get an error:

You can about 3/4 of the way down I get two errors related to: io.deb.rel.his.KafkaDatabaseHistory
Using the Kinesis source I'm not sure why it's throwing these errors related to Kafka. Does anyone have any idea why this may be happening, or a solution?
You need to specify debezium.source.database.history property for the mysql connector. Its default value is io.debezium.relational.history.KafkaDatabaseHistory, so for non-Kafka deployments please set one of the following values:
io.debezium.relational.history.FileDatabaseHistory (along with debezium.source.database.history.file.filename property);io.debezium.relational.history.MemoryDatabaseHistory for test environments.
