flink-connector-jdbc是否支持多个values问题
请问flink-connector-jdbc是否支持同时写入多个values的用法？
Re:Re:Re:回复：FlinkKafkaProducer 问题
HI,
flink 还是报以下错误：
org.apache.flink.streaming.connectors.kafka.FlinkKafkaException: Failed to send
data to Kafka: Producer attempted an operation with an old epoch. Either there
is a newer producer with the same transactionalId, or the producer's
transaction has been expired by the broker
代码如下：
Properties prop = new Properties();
prop.setProperty("bootstrap.servers", KAFKA_ADDR);
prop.setProperty("acks", "all");
//设置producer 幂等性 保证producer 数据写入到broker 不重复
prop.setProperty("enable.idempotence", "true");
// 设置FlinkKafkaProducer里面的事务超时时间，默认broker的最大事务超时时间为15分钟
prop.setProperty("transaction.timeout.ms", transaction + "");
prop.put(ProducerConfig.TRANSACTIONAL_ID_CONFIG,"my_tx_id");
prop.put(ProducerConfig.ENABLE_IDEMPOTENCE_CONFIG,true);
FlinkKafkaProducer kafkaSink = new FlinkKafkaProducer<>(
WRITE_TOPIC,
serializationSchema,
prop,
FlinkKafkaProducer.Semantic.EXACTLY_ONCE);

Re: flink任务经常性报错
这个报错的意思是有 TM 断开了连接，我觉得可以首先看看你们 'cdh02/xxx:42892' 这个丢失的 TM 的日志上有没有什么异常信息，如果没有的话也可以看看对应的机器监控有没有异常。 潘明文 于2022年3月7日周一 10:21写道： > HI 读kafka，入hbase和kafka > flink任务经常性报错 > > org.apache.flink.runtime.io.network.netty.exception.RemoteTransportException: > Connection unexpectedly closed by remote task manager 'cdh02/xxx:42892'. > This might indicate that the remote task manager was lost.
