I was looking around for a description of what flow-control there is in
nanomsg; having remembered words like high-water mark being used in
ZeroMQ. I'm interested in knowing under what (if any) circumstances
messages would be dropped on the floor.
I did see this on http://nanomsg.org/documentation-zeromq.html:
"nanomsg uses only TCP's (or equivalent's) buffers to store the data."
Does this mean that there isn't any high-water mark concept in nanomsg?
(This is probably a good thing, don't get me wrong :)
The more general version of this question is: how can avoid data loss in
the face of congestion? Does the TCP flow control mechanism serve me here?
Thanks.
Jason
