> 1. When we hit an error in producer, we call the callback with a null
> RecordMetadata. If the callback tries to get the topic/partition, it will hit
> a NullPointerException. It's probably better to create a RecordMetadata with
> -1 as the offset.
> 2. When printing out a Struct, we don't print out the content wrapped in an
> array properly. So, we will see sth like the following.

> [InFlightRequest(expectResponse=true,
> batches={test-0=RecordBatch(topicPartition=test-0, recordCount=1)},
> request=RequestSend(header={api_key=0,api_version=0,correlation_id=1,client_id=perf-test},
> body={acks=-1,timeout=3000,topic_data=[Ljava.lang.Object;@700a4488}))]
> (org.apache.kafka.clients.producer.internals.Sender)
> 3. Need to override the toString() in ProduceResponse.
> 4. Sender.run(now): It would be good to log metadata request too.
> 5. Sender.handleDisconnects(): It would be useful to log the correlation id
> of cancelled inflight requests
