Google Protocol Buffers + ChunkedWriteHandler

[이희승 (Trustin Lee)]

Hi,

I don't think it's possible to use ChunkedWriteHandler to send an individual protobuf message field.

You'd better define your protobuf message like this:

message DataResponseStart {
 required int64 timestamp = 1;
}

message DataResponseChunk {
 required bytes content = 1;
}

message DataResponseEnd {
 // or you can replace this with DataResponseChunk with a zero-byte content.
}

HTH
