[protobuf] Using CodedOutputStream to send many messages across network

[Sayan Goswami]

Hi All,

I am using CodedOutputStream and CodedInputStream to transfer messages 
across a network like so:

*Client requests:*

Socket serverSocket = new Socket(hosts, ports);

CodedOutputStream outputStream = CodedOutputStream.newInstance(serverSocket
.getOutputStream());

outputStream.flush();

CodedInputStream inputStream = CodedInputStream.newInstance(serverSocket
.getInputStream());


// the following happens inside a loop

     Request request = Request.newBuilder()

.setType(Request.RequestType.GET)

.setKey(key)

 .build();


     outputStream.writeRawVarint32(request.getSerializedSize());

     request.writeTo(outputStream);

     outputStream.flush();


*Server Processes Request:*


CodedOutputStream output = CodedOutputStream.newInstance(clientSocket
.getOutputStream());

output.flush();

CodedInputStream input = CodedInputStream.newInstance(clientSocket
.getInputStream());


int length = input.readRawVarint32();

byte[] message = input.readRawBytes(length);

Request request = Request.parseFrom(message);

// do things with request


Now, each request of mine, has a serialized size of 56.. so I can send many 
messages up the stream, but what can I do when the size limit of 64MB is 
exceeded? Is there any way to reset the buffer? Following is the error 
message I am getting:


Protocol message was too large.  May be malicious.  Use 
CodedInputStream.setSizeLimit() to increase the size limit.


Thanks,


Sayan
