Summary: [cpp] streamable message support
Key: PROTON-1988
URL: https://issues.apache.org/jira/browse/PROTON-1988
Project: Qpid Proton
Issue Type: Improvement
Components: cpp-binding
Affects Versions: proton-c-0.26.0
Reporter: Alan Conway
C++ API support for streaming large messages in chunks (too large to fit
entire message in memory)
The C link-level API does support streaming messages in chunks, but the C
message encoder/decoder and the proton::message type do. Provide an alternative
(or extended) C++ message type with a byte-stream API to send/receive the body
data in chunks, without every requiring the entire body to be held in memory.
Use cases:
# Only the message body need be streamed. Properties are encoded/decode as a
unit before sending/receiving any of the body. Most client/endpoint
applications would work this way.
# The entire message, headers, properties and all, need to be streamed, with
support for partial decoding of an incoming message and efficient pass thru
(incoming to outgoing without decode/re-encode). Only advanced intermediaries
are likely to need this (e.g. this is what dispatch router does.)
