reuse topicdata when sending producerrequest
--------------------------------------------
Key: KAFKA-289
URL: https://issues.apache.org/jira/browse/KAFKA-289
Project: Kafka
Issue Type: Improvement
Affects Versions: 0.8
Reporter: Joe Stein
Fix For: 0.8
The way that SyncProducer sends a ProducerRequest over socket is to first
serialize the whole request in a bytebuffer and then sends the bytebuffer
through socket. An alternative is to send the request like FetchReponse, using
a ProduceRequestSend that reuses TopicDataSend. This avoids code duplication
and is more efficient since it sends data in ByteBufferMessagesSet directly to
socket and avoids extra copying from messageset to bytebuffer.
