loserwang1024 opened a new pull request, #156: URL: https://github.com/apache/flink-connector-kafka/pull/156
As described in https://issues.apache.org/jira/browse/FLINK-37380 , though org.apache.flink.connector.kafka.sink.KafkaSinkBuilder#sanityCheck said "EXACTLY_ONCE delivery guarantee requires a transactionIdPrefix to be set to provide **unique transaction names across multiple KafkaSinks writing to the same Kafka cluster**., it 's no use because the transactionalIdPrefix with a default value "kafka-sink" will never be null. This PR just remove the default value, and make the sanityCheck valid. -- This is an automated message from the Apache Git Service.
