> > Before sending an actual message, kafka producer do send a (control) message of 4 bytes to the server. Kafka producer always does this action before send some message to the server.
> I think this is because in BoundedByteBufferSend.scala we do essentially
> channel.write(sizeBuffer)
> channel.write(dataBuffer)
> The correct solution is to use vector I/O and instead do
> channel.write(Array(sizeBuffer, dataBuffer))
