Summary: Infinite Loop in producing event to kafka Key: KAFKA-12990 URL: https://issues.apache.org/jira/browse/KAFKA-12990 Project: Kafka Issue Type: Bug Environment: Kafka 2.4.1 Kafka Connect 5.4.3 Reporter: Piotr Rybarczyk Marked as a bug, but depends on what configuration means. We are using AWS RDS as a Postgres database based on Postgres 11 version. We are using *Debezium 1.4.1* version with *pgoutput* and *outbox router.* Recently, I've been testing what will happen if the topic will not be configured in Kafka. Normally, in that case, connector login warns & stuck in an infinite loop as the task is unable to produce an event to Kafka: {code:java} WARN [Producer clientId=connector-producer-piotrek-test-3.outbox_events_debezium_connector-0] Error while fetching metadata with correlation id 3884 : {piotrek-test-123.partners.feature-flag-events=UNKNOWN_TOPIC_OR_PARTITION} (org.apache.kafka.clients.NetworkClient) {code} I've confirmed with the Debezium team that this issue is not in the connector logic scope. From my guess, it needs to be on Kafka or Kafka Connect level. The worst thing is that even when I've disabled the connector, & task logs still have been produced to console no matter what I've done. So in that case, we can not really on task statuses to check is pipeline working, we need to verify it on logs level.
