Send multiple messages to multiple topics in one request

[Vadim Keylis]

Version 7 of Kafka allowed to send messages to multiple topics within one
request. I assume I can do
samething in version 8, am I correct? Does my code piece look correct?
List<KeyedMessage<String, String>> topicsMsgsList = new ArrayList();
KeyedMessage<String, String> data1 = new KeyedMessage<String,
String>(topic1, msg);
KeyedMessage<String, String> data2 = new KeyedMessage<String,
String>(topic2, msg);
topicsMsgsList.add(data1);
topicsMsgsList.add(data2);
 producer.send( topicsMsgsList );

Thanks,
Vadim
