> RPC Client Improvement
> ----------------------
>
> Key: HADOOP-18536
> URL: https://issues.apache.org/jira/browse/HADOOP-18536
> Project: Hadoop Common
> Issue Type: Improvement
> Components: rpc-server
> Reporter: xinqiu.hu
> Priority: Minor
>
> In the RPC Client, before a request (including RpcRequestHeaderProto,
> RequestHeaderProto, Message Payload) is sent, they will be copied to the three
> CodedOutputStream internal byte arrays, and then aggregated to the
> ResponseBuffer
> internal byte array. Then the ResponseBuffer byte array is written to a
> BufferedOutputStream and finally to a SocketOutputStream.
> To simplify the writing process, Maybe we can copy them directly to a big
> CodedOutputStream and send them directly to the IpcStreams#out. To achieve
> this, I
> propose HADOOP-18533. But it brings the following two side effects.
> # The generic declaration of rpcRequestQueue inside Client has been changed
> to Object
> # The serialization of protobuf has been moved to rpcRequestThread, because
> rpcRequestThread is a single thread for each connection, which may have a
> performance impact.
> For the above reasons, I propose this. This pr brings the following benefits
> # For each rpc request, avoid creating a ResponseBuffer of 1024 bytes
> # For each rpc request, reduce one copy
> # For each rpc request, combine the three fragmented CodedOutputStreams into
> one
> # No side effects like HADOOP-18533
