Hi there, We are seeing WARN log traces from time to time in our Kafka producer:
2019-10-12 15:19:14:707 WARN [org.apache.kafka.clients.producer.internals.Sender] [Producer clientId=prdxpds21dsm001.prod.williamhill.plc] Got error produce response with correlation id 4899937 on topic-partition OB_SP25-3, retrying (0 attempts left). Error: UNKNOWN_PRODUCER_ID 2019-10-12 20:02:21:686 WARN [org.apache.kafka.clients.producer.internals.Sender] [Producer clientId=prdxpds21dsm001.prod.williamhill.plc] Got error produce response with correlation id 5354758 on topic-partition OB_SP87-16, retrying (0 attempts left). Error: UNKNOWN_PRODUCER_ID Does it mean producer’s metadata was removed due to retention time, and message is failed to be sent? I’m not sure but looking like happening since we enabled in producer: enable.idempotence=true Any idea?
