It seems like:
seatunnel-connectors-v2/connector-kafka/src/main/java/org/apache/seatunnel/connectors/seatunnel/kafka/sink/KafkaTransactionSender.java
the for loop never break (getEpoch() never return 0)
in public void abortTransaction(long checkpointId) {
KafkaInternalProducer<K, V> producer;
if (this.kafkaProducer != null) {
producer = this.kafkaProducer;
} else {
producer =
getTransactionProducer(
this.kafkaProperties,
generateTransactionId(this.transactionPrefix,
checkpointId));
}
for (long i = checkpointId; ; i++) {
String transactionId =
generateTransactionId(this.transactionPrefix, i);
producer.setTransactionalId(transactionId);
if (log.isDebugEnabled()) {
log.debug("Abort kafka transaction: {}", transactionId);
}
producer.abortTransaction();
producer.flush();
if (producer.getEpoch() == 0) {
break;
}
}
