Hello,
I have noticed a problem which I have also discussed with RedHat
(https://issues.redhat.com/browse/DBZ-4521):
Prerequisites:
* Debezium connector with heartbeat configuration (
"heartbeat.topics.prefix" is set)
* Heartbeat topic on Kafka side does NOT exists
* Parameter auto.create.topics is disabled (=false)
Execution:
* Connector was created
* Connector starts the heartbeat
* Connector logs the following entry: [WARN] 2022-01-06 13:25:30,094
[kafka-producer-network-thread |
connector-producer-itgermany.pmops.dispoapp.gateway.DE-350.debeziumconnector-0]
org.apache.kafka.clients.NetworkClient handleSuccessfulResponse - [Producer
clientId=connector-producer-itgermany.pmops.dispoapp.gateway.DE-350.debeziumconnector-0]
Error while fetching metadata with correlation id 38409 :
{itgermany.pmops.dispoapp.gateway.heartbeat.GatewayDepot35=UNKNOWN_TOPIC_OR_PARTITION}
* Connector status remains 'RUNNING'
* NO Data comes to Kafka via the Connector
Troubleshooting:
* Re-creating the connector caused data to be sent to Kafka for a short
time (until the heartbeat was repeated).
People from RedHat told me that they are just passing the topic name and the
message to Kafka and they do not receive a correct response
Kind Regards / Mit freundlichen Grüßen
