你好，下面2个SINK 能够并发同时处理吗？还是要窜行，等第一个SINK 好了，才能第二个SINK.
hbase 写性能
HI, 目前环境是hbase4个Region server节点，内存为128`256, 目前写入hbase7000——1多每秒,这正常，是否有调优的空间。谢谢！ 代码如下: BufferedMutatorParams params= new BufferedMutatorParams(TableName.valueOf(key)); //设置缓存10m，当达到10m时数据会自动刷到hbase params.writeBufferSize(10*1024*1024L);//设置缓存的大小 params.setWriteBufferPeriodicFlushTimeoutMs(5*1000L);//写缓存刷写时间为5s BufferedMutator mutator = connection.getBufferedMutator(params); mutator.mutate(recordList); mutator.flush(); mutator.close();

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<>(
