How to use RCF to establish long TCP connection for binary data transmission？

[wulixue]

HI.


For performance, throughput, and latency reasons, I want to do pure binary transmission, but not RPC based. Can it be implemented with RCF? If possible, what to do?

You can pass binary blobs back and forth on a RCF connection, using RCF::ByteBuffer:

ByteBuffer's are never copied, they are only reference counted, so you can move a lot of data around without incurring significant overhead. If you have a method like this:

Code: Select all

RCF_METHOD_R1(RCF::ByteBuffer, myFunc, RCF::ByteBuffer)

, then there will be no serialization overhead at all, which can make a big difference. You would just have to parse the ByteBuffer's yourself.
